Adds two post-processing flags that produce production-ready browser JS in a
single elc invocation, replacing extract-js.py in the web product pipeline:
elc --target=js --bundle --minify source.el > output.min.js
elc --target=js --bundle --obfuscate source.el > output.obf.js
--minify shells out to terser (passes=2, no drop_console, drop_debugger).
--obfuscate shells out to javascript-obfuscator with the same options as the
old extract-js.py script. --obfuscate implies --minify.
Tool discovery: checks ./node_modules/.bin/, ../node_modules/.bin/ (monorepo),
then falls back to npx. Both flags require --target=js; passing either without
it exits 1 with a clear error.
Both tools receive a reserved-names list of globals referenced from HTML
onclick= attributes (neuronDemoToggle, signInWith, NEURON_CFG, etc.) so they
are not mangled.
Implementation adds stdout_to_file(path)/stdout_restore() builtins to the C
runtime so codegen's println-streamed output can be captured to a temp file
before being piped through the external tools. Temp files use
/tmp/elc-<pid>-<timestamp>.js naming and are cleaned up on success and failure.
Rebuilds dist/platform/elc and dist/platform/elc.c. Self-hosting verified.
