The El compiler self-host has been broken since `fn main()` landed in
compiler.el. Both bootstrap.py and codegen.el skipped emitting an
`el_val_t main()` (correct - it would collide with C's int main),
but neither folded the body anywhere. The C int main() got just
runtime init + return, so any El program that put its work inside
`fn main()` produced a binary that did nothing.
Fix in two places (bootstrap.py and codegen.el, kept symmetric):
1. Capture the body of `fn main()` during the FnDef pass.
2. Emit `int main(int _argc, char** _argv)` so El programs can
declare their own local `argv` / `argc` (compiler.el itself
does this) without colliding.
3. After top-level statements, fold the captured fn main body
into C main alongside them, then return 0.
Self-host fixed point reached: gen 2 and gen 3 of compiler.el's
output are byte-identical (md5 5b4eca2a...). The new elc compiles
products/web/src/main.el natively now - 24 imports resolved, 1,173
lines of C, every imported function (page_open, nav, pricing,
checkout_page, account_page, founding_badge…) emits its forward
decl + body without a concat preprocessor in sight.
Backup of the prior self-hosted binary is at
dist/platform/elc.preselfhost in case we need to fall back.
Both bootstrap.py and compiler.el now inline every imported .el file
into a single source string before lex/parse, depth-first with set
deduplication keyed on absolute path. Two forms supported:
import "path/to/file.el" (quoted relative path)
from <module> import { ... } (bare module → <module>.el)
Strict regex matching prevents false positives like CSS keyframes
("from { opacity: 0 }") embedded in El string literals - the prior
naive str.startswith pulled '{' out as a module name and tried to
load src/{.el.
This kills the bash concat preprocessor that web/build-local.sh
needed. A web full build is now just:
python3 bootstrap.py src/main.el > dist/main.c
cc -O2 ... -o dist/neuron-web dist/main.c dist/web_stubs.c \
foundation/el/el-compiler/runtime/el_runtime.c \
-lcurl -lpthread -lssl -lcrypto
Verified end-to-end: bootstrap.py produces 1,151 lines of C from
src/main.el's 24 imports, cc links a 667 KB binary.
