Bytecode compiler now emits OP_PERFORM for (import ...) and compiles
(define-library ...) bodies. The VM stores the import request in
globals["__io_request"] and stops the run loop — no exceptions needed.
vm-execute-module returns a suspension dict, vm-resume-module continues.
Browser: sx_browser.ml detects suspension dicts from execute_module and
returns JS {suspended, op, request, resume} objects. The sx-platform.js
while loop handles cascading suspensions via handleImportSuspension.
13 modules load via .sxbc bytecode in 226ms (manifest-driven), both
islands hydrate, all handlers wired. 2650/2650 tests pass including
6 new vm-import-suspension tests.
Also: consolidated sx-platform-2.js → sx-platform.js, fixed
vm-execute-module missing code-from-value call, fixed bootstrap.py
protocol registry transpiler issues.

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.

The stepper's split-tag and steps-to-preview used (list) with append!,
but in the WASM kernel (list) creates immutable List values — append!
returns a new list without mutating, so children accumulate nowhere.
Changed all accumulator initializations to (mutable-list):
- split-tag: cch, cat, spreads
- steps-to-preview: bc-loop inner children, initial call
- result and tokens lists in the parsing setup
Also includes WASM rebuild with append! primitive and &rest fixes.

Root cause: _env_bind_hook mirrored ALL env_bind calls (including
lambda parameter bindings) to the shared VM globals table. Factory
functions like make-page-fn that return closures capturing different
values for the same param names (default-name, prefix, suffix) would
have the last call's values overwrite all previous closures' captured
state in globals. OP_GLOBAL_GET reads globals first, so all closures
returned the last factory call's values.
Fix: only sync root-env bindings (parent=None) to VM globals. Lambda
parameter bindings stay in their local env, found via vm_closure_env
fallback in OP_GLOBAL_GET.
Also in this commit:
- OP_CLOSURE propagates parent vm_closure_env to child closures
- Remove JIT globals injection (closure vars found via env chain)
- sx_server.ml: SX-Request header → returns text/sx (aser only)
- sx_server.ml: diagnostic endpoint GET /sx/_debug/{env,eval,route}
- sx_server.ml: page helper stubs for deep page rendering
- sx_server.ml: skip client-libs/ dir (browser-only definitions)
- adapter-html.sx: unknown components → HTML comment (not error)
- sx-platform.js: .sxbc fallback loader for bytecode modules
- Delete sx_http.ml (standalone HTTP server, unused)
- Delete stale .sxbc.json files (arity=0 bug, replaced by .sxbc)
- 7 new closure isolation tests in test-closure-isolation.sx
- mcp_tree.ml: emit arity + upvalue-count in .sxbc.json output

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.

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).
