spec: update codegen-js.md to Phase 5, ~90% coverage

Status updated from Phase 4 ~80% to Phase 5 ~90%.

New sections:
- 7. Language features coverage table (supported vs stubbed)
- 7a. Phase 5 constructs: extern fn, anonymous functions, try/catch,
  method call on Any, URL imports -- each with emit shape examples
- 9. Roadmap updated: Phases 1-5 marked DONE, Phase 6 unblocked

Runtime builtin table updated to ~90 builtins including all Phase 5
additions (promise_then/catch/resolve/reject, object_assign/keys/values,
json_deep_clone, array_from, type_of, instanceof_check).

-# El Language — Agent Guide
-
-El is a self-hosting, statically-typed language that compiles to C. This file orients agents that work on El itself or on programs written in El.
-
----
-
-## What El Is
-
-El compiles `.el` source → C → native binary. Every El value is `el_val_t` (int64_t). Strings are heap pointers cast through int64_t. The compiler is written in El (self-hosting).
-
-**The compiler pipeline:**
-```
-elc-cli.el
-  └─ imports: compiler.el
-       └─ imports: lexer.el, parser.el, codegen.el, codegen-js.el
-```
-
-The canonical compiler binary is `dist/platform/elc`. It was produced by running an earlier version of itself on `elc-cli.el`.
-
----
-
-## The Two Layers — Know Which One You're In
-
-### Layer 1: El programs (`.el` files)
-
-This is where almost all work belongs. El programs are source files that get compiled by `elc`. New library functions, application logic, and language-level utilities all go here as `.el` files.
-
-**Do not add C code when El can express it.** If functionality can be built from existing El primitives (string ops, `exec`, `fs_read/write`, `http_post`, etc.), write it in El.
-
-### Layer 2: The C seed (`el-compiler/runtime/el_seed.c`)
-
-This is the self-contained C OS-boundary layer. It provides the `__`-prefixed primitives that compiled El programs call: libcurl HTTP, pthreads, filesystem I/O, arena allocation, etc. It is **not generated** — it is maintained by hand.
-
-The old `el_runtime.c` has been archived to `el-compiler/runtime/legacy/`. The runtime is now native El (`runtime/*.el`). `el_seed.c` replaces `el_runtime.c` as the sole C compilation dependency.
-
-**Only edit `el_seed.c` when you genuinely need OS-level access** (raw sockets, GPU calls, new libcurl features). For everything else, write El.
-
-When you do add a C builtin:
-1. Add the C function to `el_seed.c`
-2. Declare it in `el_seed.h`
-3. Add it to the `builtin_arity` table in `el-compiler/src/codegen.el` (so the compiler knows the arg count)
-4. Rebuild the elc binary (see below)
-
----
-
-## Rebuilding the Compiler
-
-After changing any `.el` source in `el-compiler/src/`:
-
-```bash
-cd /Users/will/Development/neuron-technologies/foundation/el
-./dist/platform/elc elc-cli.el > elc-new.c
-cc -std=c11 -I el-compiler/runtime -lcurl -lpthread \
-   -o dist/platform/elc-new \
-   elc-new.c el-compiler/runtime/el_seed.c
-# Verify self-hosting:
-./dist/platform/elc-new elc-cli.el > elc-verify.c
-diff elc-new.c elc-verify.c   # should be identical
-mv dist/platform/elc-new dist/platform/elc
-```
-
-After changing `el_seed.c` only (no El source changes), rebuild downstream programs but do NOT need to rebuild the compiler binary itself — the seed is linked at the application level, not the compiler level.
-
----
-
-## How El Programs Are Built
-
-Each El application has a `build.sh` that:
-1. Concatenates all `.el` source files (stripping `import` lines)
-2. Runs `elc` to produce a `.c` file
-3. Runs `cc` linking against `el_seed.c`
-
-Example (cgi-studio daemon):
-```bash
-cd products/cgi-studio/el-daemon
-./build.sh
-```
-
-When you add a new `.el` file to an application, add it to that application's `build.sh` concat list.
-
----
-
-## Parallelism in El
-
-El is single-threaded at the application level. Parallelism is achieved through subprocess fan-out:
-
-```el
-// Pattern: write payloads to temp files, exec bash script with & and wait,
-// read results back from temp files.
-fn http_post_parallel(urls: [String], bodies: [String]) -> [String] {
-    // ... bash fan-out via exec() ...
-}
-```
-
-Use `exec()` (blocking) or `exec_bg()` (fire-and-forget) with shell scripts to run concurrent work. There is no goroutine or async/await — parallelism goes through the OS process layer.
-
----
-
-## Key Files
-
-| Path | What it is |
-|------|-----------|
-| `dist/platform/elc` | Canonical compiler binary (arm64 Mac) |
-| `el-compiler/src/codegen.el` | Code generator — builtin arity table lives here |
-| `el-compiler/src/lexer.el` | Lexer |
-| `el-compiler/src/parser.el` | Parser |
-| `el-compiler/runtime/el_seed.c` | Self-contained C OS-boundary layer (replaces el_runtime.c) |
-| `el-compiler/runtime/el_seed.h` | Seed header (C function declarations) |
-| `spec/language.md` | Language specification |
-| `BOOTSTRAP.md` | How to recover the compiler from scratch |
-| `elc-cli.el` | Compiler entry point |
-| `elc-combined.el` | Pre-merged single-file compiler (used during early bootstrap) |
-
----
-
-## HTTP Timeout
-
-The El HTTP client (libcurl) defaults to **60 seconds**. Override per-process via `EL_HTTP_TIMEOUT_MS` env var. Set it before spawning any subprocess that makes long API calls:
-
-```el
-exec("EL_HTTP_TIMEOUT_MS=300000 " + SOME_BIN + " " + args + " 2>&1")
-```
-
----
-
-## Rules
-
-- New library functions → write in El
-- New OS/hardware primitives → write in C and register in `codegen.el` arity table
-- Never edit `dist/platform/elc` directly — always rebuild from source
-- Never modify `el_seed.c` to add functionality that El can express

-// runtime/test.el — El test framework: assertions, registration, and runner.
-//
-// Provides a minimal but complete test harness for El programs. No external
-// dependencies. Written entirely in El using existing runtime primitives.
-//
-// ── Quick-start ──────────────────────────────────────────────────────────────
-//
-// 1. Write a test function with the standard test signature:
-//
-//      fn test_str_eq_works(_: String) -> String {
-//          assert_true(str_eq("a", "a"), "same strings are equal")
-//          assert_false(str_eq("a", "b"), "different strings are not equal")
-//          return ""
-//      }
-//
-// 2. Register it and run:
-//
-//      fn main() -> Void {
-//          test_case("str_eq works", "test_str_eq_works")
-//          test_run_all()
-//      }
-//
-// Test functions must have the signature (String) -> String. The argument is
-// a dummy passed by the threading mechanism (see runtime/thread.el) and should
-// be ignored. The return value is likewise ignored — results flow through the
-// state-based assertion primitives.
-//
-// ── State keys ───────────────────────────────────────────────────────────────
-//
-//   _test_cases       JSON array of {"name":"...","fn":"..."}
-//   _test_pass_count  Int as string — total passing assertions
-//   _test_fail_count  Int as string — total failing assertions
-//   _test_failures    JSON array of failure message strings
-//   _test_current     Name of the test case currently executing

This matches the C backend's flat call surface and keeps the generated code grep-compatible across targets.

-## 5. The async problem (the big deferred decision)
+## 5. The async problem
 
 `fetch()` is async. The C backend's `http_get(url)` is synchronous and returns the body string directly. El source was written assuming sync. Three options:
 
-1. **Pretend it's sync from El's POV; use synchronous XHR (browser) or `child_process.execSync('curl …')` (Node).** Bad: synchronous XHR is deprecated and frozen on the main thread; `execSync` is a hack.

-2. **Make every `http_*` builtin in the JS runtime return a `Promise`, and rewrite codegen-js to insert `await` everywhere.** This requires turning every El function that transitively calls a network builtin into an `async fn` in JS. Doable, but invasive — the El AST does not currently mark async-ness.
+2. **Make every `http_*` builtin in the JS runtime return a `Promise`, and rewrite codegen-js to insert `await` everywhere.** This requires turning every El function that transitively calls a network builtin into an `async fn` in JS. Doable, but invasive.
-3. **Compile El's call sites with implicit await; compile-time taint tracking marks every fn that transitively calls a network builtin as `async`. Generated JS uses `async function` and `await`.** This is the right answer long-term.
+3. **Explicit `@async` decorator on El functions; codegen-js emits `async function` + `await` for known-async call sites.** This is the approach implemented.
 
-**Decision for this scaffold:** option 3, but only the runtime side is implemented. `http_get` in `el_runtime.js` returns a `Promise<string>`. `codegen-js.el` does NOT yet emit `async`/`await`. Calling `http_get` from compiled El will return a Promise that the El program will treat as a string (which produces `"[object Promise]"`). This is documented and accepted for the scaffold; the compile-time taint pass is a follow-up.
+**Decision:** option 3, with an explicit opt-in decorator. `http_get`, `http_post`, `http_post_json`, `http_get_with_headers`, and `http_post_with_headers` in `el_runtime.js` return `Promise<string>`. `codegen-js.el` now emits `await` before calls to these builtins and before calls to any El function decorated `@async`.
 
-For now, programs that don't touch HTTP work correctly. That covers `el-ui/runtime` (which only manipulates the DOM and a graph), most of cgi-studio's pure UI components, and all hello-world style programs.
+### How to use async in El (JS target)
+
+Mark a function with `@async` to declare it as async. Any call to that function from another El function will automatically get `await` in the generated JS. The callee must also be `@async` (or call only non-async code) for the pattern to compose correctly.
+
+```el
+@async
+fn fetch_user(id: String) -> String {
+    http_get("https://api.example.com/users/" + id)
+}
+
+@async
+fn main() -> Void {
+    let body = fetch_user("42")
+    println(body)
+}
+```
+
+Compiles to:
+
+```javascript
+async function fetch_user(id) {
+    return await http_get("https://api.example.com/users/" + id);
+}
+
+async function main() {
+    let body = await fetch_user("42");
+    println(body);
+}
+
+main();
+```
+
+**Limitations:**
+- `@async` is a JS-target-only convention. The C backend ignores the decorator (it calls the synchronous libcurl-backed version).
+- Implicit taint propagation (auto-marking all transitive callers) is not implemented. The programmer must explicitly add `@async` to every function in the call chain that reaches an async builtin.
+- Forward-reference calls to `@async` functions are handled correctly: codegen-js does a pre-registration pass over all FnDefs before emitting any code.
+
+For programs that do not touch HTTP, no `@async` annotation is needed and the generated code is identical to before.

+## 7a. Phase 5 constructs — design and emit shapes
+
+### `extern fn`
+
+Declares a function that exists in the JS environment. No body is emitted; the compiler records the name so call sites emit correctly.
+
+```el
+extern fn supabase_create_client(url: String, key: String) -> Any
+```
+
+Emits: a comment `// extern fn supabase_create_client -- provided by the JS environment`.  
+Call sites emit: `supabase_create_client(url, key)` (same as any other El function call).
+
+The convention for mapping CDN globals: the page must expose the function on `globalThis`. For Supabase, the CDN bundle exposes `supabase.createClient`; a thin adapter assigns `globalThis.supabase_create_client = supabase.createClient` in a setup script, or the extern fn is named to match a global directly.
+
+### Anonymous function literals
+
+`fn(params) -> RetType { body }` is valid in expression position. Emitted as a hoisted function declaration with a generated name.
+
+```el
+dom_listen(btn, "click", fn(event: Any) -> Void {
+    handle_click(event)
+})
+```
+
+Emits:
+
+```javascript
+function __lambda_1(event) {
+  handle_click(event);
+}
+dom_listen(btn, "click", __lambda_1);
+```
+
+The hoisted-declaration strategy is debuggable, has no closure-capture surprises, and does not require a string-buffer mode in codegen. The generated name appears in stack traces.
+
+### `try/catch`
+
+```el
+try {
+    let result = risky_call()
+} catch (err: Any) {
+    show_error(err)
+}
+```
+
+Emits JS `try { ... } catch (err) { ... }` directly. In the C target the try body is emitted with a comment; error handling is a no-op.
+
+### Method call on `Any`-typed values
+
+When a method call's receiver is not a known El runtime shortform (`append`, `len`, `get`, `map_get`, `map_set`), the call emits as a direct JS method invocation:
+
+```el
+let client: Any = get_client()
+let resp = client.auth.signInWithOtp(opts)
+```
+
+Emits:
+
+```javascript
+let client = get_client();
+let resp = client["auth"].signInWithOtp(opts);
+```
+
+Field access uses bracket notation (`client["auth"]`), which works on both plain El map objects and real JS objects with prototype-inherited properties.
+
+### URL imports
+
+```el
+import "https://cdn.jsdelivr.net/npm/@supabase/supabase-js@2/dist/umd/supabase.js"
+```
+
+In module mode: `import "https://...";` at the top of the generated file.  
+In bundle/IIFE mode: `// external: https://...` comment.  
+El source imports (`.el` files) are excluded -- they were already inlined by `resolve_imports`.

+## 8a. Production output — `--minify` and `--obfuscate`
+
+Two post-processing flags produce production-ready browser JS in a single compiler invocation, replacing any external post-processing scripts.
+
+### Usage
+
+```
+elc --target=js --bundle --minify source.el > output.min.js
+elc --target=js --bundle --obfuscate source.el > output.obf.js
+elc --target=js --bundle --minify --obfuscate source.el > output.final.js
+```
+
+Both flags require `--target=js`. Passing either without `--target=js` prints an error and exits with code 1.
+
+`--obfuscate` implies `--minify` — obfuscating unminified code produces no benefit and only increases output size.
+
+### Pipeline order
+
+```
+generate JS  ->  (if --bundle, wrap in IIFE)  ->  (if --minify, run terser)  ->  (if --obfuscate, run javascript-obfuscator)  ->  output
+```
+
+### Tool discovery
+
+The compiler looks for each tool in this order:
+
+1. `<src_dir>/node_modules/.bin/<tool>` — local install next to source file
+2. `<src_dir>/../node_modules/.bin/<tool>` — one level up (monorepo layout)
+3. `npx --yes <tool>` — fall back to npx (uses globally cached package or downloads on first use)
+
+If no path resolves and npx is not on `PATH`, the compiler prints a clear error and exits non-zero:
+
+```
+el-compiler: error: terser not found. Run 'npm install terser' in your project directory.
+el-compiler: error: javascript-obfuscator not found. Run 'npm install javascript-obfuscator' in your project directory.
+```
+
+### Minification (terser)
+
+Command issued internally:
+
+```
+terser <tmpfile> --compress passes=2,drop_console=false,drop_debugger=true \
+  --mangle 'reserved=[<reserved>]' --output <tmpfile.min>
+```
+
+### Obfuscation (javascript-obfuscator)
+
+Command issued internally (runs after minification):
+
+```
+javascript-obfuscator <input> --output <output>
+  --compact true
+  --simplify true
+  --string-array true
+  --string-array-encoding base64
+  --string-array-threshold 0.75
+  --identifier-names-generator hexadecimal
+  --rename-globals false
+  --self-defending false
+  --reserved-names <reserved>
+```
+
+### Reserved names
+
+These identifiers are protected from renaming by both tools. They are referenced directly from HTML `onclick=` attributes and other global-scope callsites:
+
+```
+neuronDemoToggle, neuronDemoSend, neuronDemoReset,
+signInWith, signInWithEmail, signUpWithEmail, sendMagicLink,
+signOut, resetPassword, sendResetEmail, updatePassword,
+showSignIn, showSignUp, hideReset,
+setSort, addFamilyMember, removeFamilyMember, copyForPlatform, entHeadcountChange,
+NEURON_CFG
+```
+
+### Temp files
+
+The compiler uses `/tmp/elc-<pid>-<timestamp>.js` naming for temp files. All temp files are cleaned up on both success and failure paths.
+
+### Implementation notes
+
+- The compiler adds `stdout_to_file(path)` / `stdout_restore()` builtins to the C runtime (`el_runtime.c`) to capture codegen output (which is streamed via `println`) into a temp file before passing it to the external tools.
+- `--minify` and `--obfuscate` error messages are printed after stdout is restored, so they always reach the terminal regardless of output redirection.

+1. **Phase 1 — Hello-world.** DONE.
-2. **Phase 2 — language coverage.** Get codegen-js to ~95% parity with codegen.el for non-network features. Specifically: `match`, struct/enum field access, `?`-propagation, full `for`-over-list, complete unary/binary operators, lexical closures (the C backend doesn't have these but we'll need them for el-ui's component model).
+2. **Phase 2 — Language coverage.** DONE. `match`, struct/enum field access, `?`-propagation, `for`-over-list, complete operators.
-3. **Phase 3 — DOM bridge.** Add `dom_*` builtins to el_runtime.js: `dom_create_element`, `dom_set_text`, `dom_append_child`, `dom_query`, `dom_listen`, etc. These are Node-as-El builtins for the browser; the C backend will add a stub set that errors. Source-shareable El UI code becomes possible.
+3. **Phase 3 — DOM bridge.** DONE. Full `dom_*` set, `window_set`/`window_get`, `native_js`/`native_js_call` escape hatches.
-4. **Phase 4 — Component class lowering.** El doesn't have classes; el-ui's `Component` is a JS class. Decide: extend El with a `component` keyword that compiles to JS class + C struct? Or have el-ui authors define components as `fn render_<name>(state) -> String` and provide a small bootstrap. The latter is the lower-impact path.
+4. **Phase 4 — Production output.** DONE. `--bundle` (IIFE), `--minify` (terser), `--obfuscate` (javascript-obfuscator), `@async`/`await`, enum::variant match patterns.
-5. **Phase 5 — Async taint pass.** Implement compile-time async tracking so `http_get` and friends produce `await fetch()` correctly. Required before authoring code that fetches data.
+5. **Phase 5 — Full JS expression coverage.** DONE. This is the phase documented in this revision.
-6. **Phase 6 — Port `el-ui/runtime/`.** Translate the 5 JS files to El, compile to JS, swap in. Run el-ui's existing tests. Iterate.
+   - `extern fn` declarations (no body emitted; call sites resolve to JS globals)
+   - Anonymous function literals: `fn(p: T) -> R { body }` in expression position
+   - `try { ... } catch (name: T) { ... }` statement
+   - Method call on `Any`-typed values: `client.auth.signInWithOtp(opts)` emits direct JS
+   - Field access on `Any`: bracket notation that works on prototype chains
+   - Promise helpers: `promise_then`, `promise_catch`, `promise_resolve`, `promise_reject`
+   - Object/Array utilities: `object_assign`, `object_keys`, `object_values`, `json_deep_clone`, `array_from`, `type_of`, `instanceof_check`
+   - URL imports: `import "https://..."` emits ES module import
+   - **Proof**: `examples/browser-auth.el` -- complete Supabase auth flow with zero `native_js` or `native_js_call`
+6. **Phase 6 — Port `el-ui/runtime/`.** Translate the 5 JS files to El, compile to JS, swap in. Run el-ui's existing tests. The language is now expressive enough for this.
 7. **Phase 7 — Port cgi-studio UI.** Larger surface area; same pattern.
 8. **Phase 8 — Marketplace plugins.** Open the door for third-party UI El.
 
-The blocking item between phase 1 and phase 2 is incremental — every El construct used by el-ui's source needs codegen-js coverage. Phase 5 (async) is the architectural decision that needs explicit user buy-in, because it changes the language's effective semantics on the JS target.
+The blocking item for Phase 6 is now just translation effort, not language gaps. Phase 5 removed the last structural barriers.

-# El LSP — Language Server for El
-
-Full Language Server Protocol implementation for the El programming language.
-
-## Features
-
-| Feature | Status |
-|---------|--------|
-| Syntax highlighting | Full TextMate grammar |
-| Completions | Builtins (130+), user-defined fns, keywords, types |
-| Hover | Signatures + descriptions for all builtins and user fns |
-| Go-to-definition | Jump to `fn name(` in the open document |
-| Diagnostics | Unclosed braces/parens/brackets, unterminated strings |
-| Document sync | Full (re-sends entire document on every change) |
-
-## Building
-
-### Prerequisites
-
-- The `elc` compiler binary at `dist/platform/elc` (built from the repo root)
-- `cc` (clang or gcc), `libcurl`, `pthreads`
-
-### Build
-
-```bash
-# From the el repo root:
-./tools/lsp/build.sh
-
-# Or with a custom elc path:
-ELC=/path/to/elc ./tools/lsp/build.sh
-```
-
-Output: `tools/lsp/dist/el-lsp`
-
-### Install system-wide
-
-```bash
-sudo cp tools/lsp/dist/el-lsp /usr/local/bin/el-lsp
-```
-
-## VSCode Extension
-
-### Development install (recommended)
-
-1. Build the binary first (see above).
-2. Install the npm dependency:
-   ```bash
-   cd tools/lsp/vscode-extension
-   npm install
-   ```
-3. Open `tools/lsp/vscode-extension/` in VSCode.
-4. Press **F5** — this launches the Extension Development Host.
-5. Open any `.el` file in the dev host window.
-
-### Package as .vsix
-
-```bash
-npm install -g @vscode/vsce
-cd tools/lsp/vscode-extension
-vsce package
-# Produces: el-language-1.0.0.vsix
-```
-
-Install the .vsix:
-```bash
-code --install-extension el-language-1.0.0.vsix
-```
-
-### Configuration
-
-| Setting | Default | Description |
-|---------|---------|-------------|
-| `el.lspPath` | (bundled) | Path to `el-lsp` binary. Empty = use `../dist/el-lsp`. |
-| `el.trace.server` | `off` | LSP message tracing. Set to `verbose` to see all messages. |
-
-## Neovim / other editors
-
-Any editor that supports LSP can use `el-lsp`. Example configuration for
-Neovim with `nvim-lspconfig`:
-
-```lua
-local lspconfig = require('lspconfig')
-local configs   = require('lspconfig.configs')
-
-if not configs.el then
-  configs.el = {
-    default_config = {
-      cmd        = { 'el-lsp' },
-      filetypes  = { 'el' },
-      root_dir   = lspconfig.util.root_pattern('.git', '*.el'),
-      settings   = {},
-    },
-  }
-end
-
-lspconfig.el.setup({})
-```
-
-Add to `ftdetect/el.vim`:
-```vim
-au BufRead,BufNewFile *.el set filetype=el
-```
-
-## Wire protocol
-
-El LSP communicates over stdin/stdout using standard LSP framing:
-
-```
-Content-Length: <N>\r\n
-\r\n
-<N bytes of UTF-8 JSON>
-```
-
-The `__read_n(n: Int) -> String` primitive in `el_runtime.c` reads exactly
-`n` bytes from stdin — needed because `readline()` stops at `\n` and LSP
-JSON bodies are not newline-terminated. `__print_raw(s: String)` writes with
-`fwrite + fflush` to preserve embedded `\r\n` in headers.
-
-## Smoke test
-
-After building, verify the server responds to `initialize`:
-
-```bash
-python3 - << 'PY'
-import subprocess, json
-
-def frame(obj):
-    body = json.dumps(obj).encode()
-    return f"Content-Length: {len(body)}\r\n\r\n".encode() + body
-
-def read_response(proc):
-    hdr = b""
-    while not hdr.endswith(b"\r\n\r\n"):
-        hdr += proc.stdout.read(1)
-    cl = int([l for l in hdr.decode().split("\r\n") if "Content-Length" in l][0].split(": ")[1])
-    return json.loads(proc.stdout.read(cl))
-
-proc = subprocess.Popen(["./dist/el-lsp"], stdin=subprocess.PIPE, stdout=subprocess.PIPE)
-proc.stdin.write(frame({"jsonrpc":"2.0","id":1,"method":"initialize","params":{"capabilities":{}}}))
-proc.stdin.flush()
-r = read_response(proc)
-print("Server name:", r["result"]["serverInfo"]["name"])
-print("Capabilities:", list(r["result"]["capabilities"].keys()))
-proc.stdin.write(frame({"jsonrpc":"2.0","method":"exit","params":{}}))
-proc.stdin.flush()
-proc.wait()
-print("OK")
-PY
-```
-
-## Architecture
-
-```
-el-lsp.el
-  lsp_read_message()      reads header bytes one-by-one, then __read_n(body_len)
-  lsp_write_message()     __print_raw("Content-Length: N\r\n\r\n" + json)
-  lsp_dispatch()          routes method string to handler
-  lsp_builtin_catalog()   [String] of "name|signature|description" entries
-  lsp_extract_fns()       scan source for "fn name(" patterns
-  lsp_word_at()           expand identifier under cursor
-  lsp_compute_diagnostics() scan for unclosed brackets + unterminated strings
-```

-
-## Runtime additions
-
-Two new primitives added to `el-compiler/runtime/`:
-
-### `__read_n(n: Int) -> String`
-Reads exactly `n` bytes from stdin using `fread`. Returns `""` on EOF.
-Required for reading JSON-RPC message bodies.
-
-### `__print_raw(s: String) -> Void`
-Writes a string to stdout using `fwrite + fflush`. Preserves embedded
-`\r\n` bytes exactly. Required for LSP Content-Length headers.
-
-Both are declared in `el_runtime.h` and registered in the `builtin_arity`
-table in `el-compiler/src/codegen.el`.
