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.

highlight.sx now returns a list of (span :class "..." "text") elements
instead of a string. The rendering pipeline handles the rest:
- Server render-to-html: produces <span class="...">text</span>
- Client render-to-dom: produces DOM span elements
- Aser: serializes spans as SX for client rendering
Key fixes:
- hl-span uses (make-keyword "class") not :class (keywords evaluate
to strings in list context)
- render-sx-tokens returns flat list of spans (no wrapper)
- hl-escape is identity (no escaping needed for tree values)
- highlight.sx added to browser bundle + platform loader
- ~docs/code renders src directly as child of pre

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).
