perf: 81% RSS reduction — el_release, arena scoping, streaming codegen, libcurl stub

Browse Source

Chain of optimizations from swarm rounds 4-7:
- Flat stride-2 token list: eliminate per-token Map allocation (~112B each × N tokens)
- Systematic el_release() in parser.el: eagerly free intermediate parse result maps
- Per-function and per-statement arena scoping in codegen_streaming()
- Streaming codegen pipeline: parse one fn at a time, emit C, discard AST
- HAVE_CURL guard: elc CLI binary drops libcurl, eliminating SSL/TLS init overhead
- HTML codegen parts-list: O(n) instead of O(n²) string growth for nested templates
- Batch c_escape: str_slice clean runs instead of char-at per byte

Result: 33.4MB → 6.5MB RSS on web/src/main.el (-81%). Self-host: PASS.
