fc2b5e502f 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)

7b4c918773 Recompile all 26 .sxbc with define-library wrappers + fix eval/JIT 
All 26 browser modules recompiled with define-library/import forms.
Compilation works without vm-compile-adapter (JIT pre-compilation
hangs with library wrappers in some JIT paths — skipped for now,
CEK compilation is ~34s total).

Key fixes:
- eval command: import-aware loop that handles define-library/import
  locally without touching the Python bridge pipe (avoids deadlock)
- compile-modules.js: skip vm-compile-adapter, bump timeout

2621/2621 OCaml tests passing.

951b3a6586 Native bytecode compilation in MCP: 108s → 1.9s (57x faster) 
Replace Node.js compile-modules.js with direct Sx_compiler.compile_module
calls in mcp_tree.ml. No subprocess, no JIT warm-up, no Node.js.
23 files compile in 1.9 seconds.

Also includes rebuilt WASM kernel (iterative cek_run) and all 23
bytecode modules recompiled with native compiler.

e0070041d6 Add .sxbc s-expression bytecode format 
Bytecode modules are now serialized as s-expressions (.sxbc) in addition
to JSON (.sxbc.json). The .sxbc format is the canonical representation —
content-addressable, parseable by the SX parser, and suitable for CID
referencing. Annotation layers (source maps, variable names, tests, docs)
can reference the bytecode CID without polluting the bytecode itself.

Format: (sxbc version hash (code :arity N :bytecode (...) :constants (...)))

The browser loader tries .sxbc first (via load-sxbc kernel primitive),
falls back to .sxbc.json. Caddy needs .sxbc MIME type to serve the new
format (currently 404s, JSON fallback works).
