vm.sx feature parity: JIT dispatch, active VM tracking, CEK fallback
Add missing features to lib/vm.sx that sx_vm.ml has:
- *active-vm* mutable global for HO primitive callback VM reuse
- *jit-compile-fn* platform-settable JIT compilation hook
- try-jit-call: check lambda-compiled, attempt JIT, fallback to CEK
- vm-call: VmClosure→push-frame, Lambda→try-jit, Component→CEK
- vm-call-closure: save/restore *active-vm* around execution
- vm-push-frame: refactored to use accessor functions
- cek-call-or-suspend: preamble-provided CEK interop
Transpiled output (sx_vm_ref.ml) now has 12 functions (was 9):
*active-vm*, *jit-compile-fn*, try-jit-call, vm-call,
vm-resolve-ho-form, vm-call-external, env-walk, env-walk-set!,
vm-run, vm-step, vm-call-closure, vm-execute-module
48 preamble functions (native OCaml type access).

Step 5p6 lazy loading + Step 6b VM transpilation prep
Lazy module loading (Step 5 piece 6 completion):
- Add define-library wrappers + import declarations to 13 source .sx files
- compile-modules.js generates module-manifest.json with dependency graph
- compile-modules.js strips define-library/import before bytecode compilation
(VM doesn't handle these as special forms)
- sx-platform.js replaces hardcoded 24-file loadWebStack() with manifest-driven
recursive loader — only downloads modules the page needs
- Result: 12 modules loaded (was 24), zero errors, zero warnings
- Fallback to full load if manifest missing
VM transpilation prep (Step 6b):
- Refactor lib/vm.sx: 20 accessor functions replace raw dict access
- Factor out collect-n-from-stack, collect-n-pairs, pad-n-nils helpers
- bootstrap_vm.py: transpiles 9 VM logic functions to OCaml
- sx_vm_ref.ml: proof that vm.sx transpiles (preamble has stubs)
