giles fb30351be2 Post-10d: JIT measurement infrastructure + compiler fixes

Measurement:
- JIT hit/miss/skip counters in sx_runtime.ml (jit_try_call)
- VM instruction counter enabled in run loop
- jit-enable, vm-counters, vm-counters-reset epoch commands
- Test runner --jit flag for opt-in JIT measurement
- Results (132 tests): 5.8% VM hit, 56% evaluator self-calls, 38% anon

Fixes:
- Move compile-provide, compile-scope, compile-guard,
  compile-guard-clauses inside define-library begin block
  (were orphaned outside, causing "Undefined symbol" JIT failures)
- Add deref primitive (signal unwrap with tracking)
- Add deref compiler dispatch
- Fix compile-expr for scope forms to handle non-keyword args

CEK pruning assessment: evaluator self-calls (56%) can't be pruned —
the CEK must evaluate itself. Real pruning requires self-hosting
compiler (Phase 2+). The VM correctly handles user code that
JIT-compiles. 2776/2776 tests pass.
