JIT allowlist (sx_server.ml):
- Replace try-every-lambda strategy with StringSet allowlist. Only
functions in the list get JIT compiled (compiler, parser, pure transforms).
Render functions that need dynamic scope skip JIT entirely — no retry
overhead, no silent fallbacks.
- Add (jit-allow name) command for dynamic expansion from Python bridge.
- JIT failures log once with "[jit] DISABLED fn — reason" then go silent.
Standalone --test mode (sx_server.ml):
- New --test flag loads full env (spec + adapters + compiler + signals),
supports --eval and --load flags. Quick kernel testing without Docker.
Example: dune exec bin/sx_server.exe -- --test --eval '(len HTML_TAGS)'
Integration tests (integration_tests.ml):
- New binary exercising the full rendering pipeline: loads spec + adapters
into a server-like env, renders HTML via both native and SX adapter paths.
- 26 tests: HTML tags, special forms (when/if/let), letrec with side
effects, component rendering, eval-expr with HTML tag functions.
- Would have caught the "Undefined symbol: div/lake/init" issues from
the previous commit immediately without Docker.
VM cleanup (sx_vm.ml):
- Remove temporary debug logging (insn counter, call_closure counter,
VmClosure depth tracking) added during debugging.
