efd0d9168f Step 7d complete: exhaustive match checking + evaluator cleanup 
Match exhaustiveness analysis:
- check-match-exhaustiveness function in evaluator.sx
- lint-node in tree-tools.sx checks match forms during format-check
- Warns on: no wildcard/catch-all, boolean missing true/false case
- (match x (true "yes")) → "match may be non-exhaustive"

Evaluator cleanup:
- Added missing step-sf-callcc definition (was in old transpiled output)
- Added missing step-sf-case definition (was in old transpiled output)
- Removed protocol functions from bootstrap skip set (they transpile fine)
- Retranspiled VM (bootstrap_vm.py) for compatibility

2650 tests pass (+5 from new features).

All Step 7 features complete:
  7a: ->> |> as-> pipe operators
  7b: Dict patterns, &rest, let-match destructuring
  7c: define-protocol, implement, satisfies?
  7d: Exhaustive match checking

e46cdf3d4d Wire transpiled VM as active execute_module — 2644 tests pass 
The transpiled VM (sx_vm_ref.ml, from lib/vm.sx) is now the ACTIVE
bytecode execution engine. sx_server.ml and sx_browser.ml call
Sx_vm_ref.execute_module instead of Sx_vm.execute_module.

Results:
- OCaml tests: 2644 passed, 0 failed
- WASM tests: 32 passed, 0 failed
- Browser: zero errors, zero warnings, islands hydrate
- Server: pages render, JIT compiles, all routes work

The VM logic now lives in ONE place: lib/vm.sx (SX).
OCaml gets it via transpilation (bootstrap_vm.py).
JS/browser gets it via bytecode compilation (compile-modules.js).

54ee673050 Transpiled VM compiles with real native preamble 
bootstrap_vm.py preamble now has real implementations for all 48
native OCaml functions: stack ops, frame access, upvalue capture,
closure creation, JIT dispatch, CEK fallback, env walking.

The transpiled sx_vm_ref.ml (25KB) compiles cleanly alongside
sx_vm.ml. 7 logic functions transpiled from vm.sx:
  vm-call, vm-resolve-ho-form, vm-call-external,
  vm-run, vm-step, vm-call-closure, vm-execute-module

Next: wire callers to use Sx_vm_ref instead of Sx_vm.
