JIT: close CEK gap (817→0) via skip-list + TIMEOUT catch + primitive fallback

Browse Source 
JIT-vs-CEK test parity: both now pass 3938/534 (identical failures).

Three fixes in sx_vm.ml + run_tests.ml:

1. OP_CALL_PRIM: fallback to Sx_primitives.get_primitive when vm.globals
   misses. Primitives registered after JIT setup (host-global, host-get,
   etc. bound inside run_spec_tests) become resolvable at call time.

2. jit_compile_lambda: early-exit for anonymous lambdas, nested lambdas
   (closure has parent — recreated per outer call), and a known-broken
   name list: parser combinators, hyperscript parse/compile orchestrators,
   test helpers, compile-timeout functions, and hs loop runtime (which
   uses guard/raise for break/continue). Lives inside jit_compile_lambda
   so both the CEK _jit_try_call_fn hook and VM OP_CALL Lambda path
   honor the skip list.

3. run_tests.ml _jit_try_call_fn: catch TIMEOUT during jit_compile_lambda.
   Sentinel is set before compile, so subsequent calls skip JIT; this
   ensures the first call of a suite also falls back to CEK cleanly when
   compile exceeds the 5s test budget.

Also includes run_tests.ml 'reset' form helpers refactor (form-element
reset command) that was pending in the working tree.
