Revert (when (client?) ...) guard in signals.sx — it broke JS tests
since client? is false in Node.js too.
Instead, rebind effect and register-in-scope as no-ops in sx_server.ml
AFTER all .sx files load. The SX definition from signals.sx is replaced
only in the OCaml SSR context. JS tests and WASM browser keep the real
effect implementation.
Remove redundant browser primitive stubs from sx_primitives.ml — only
resource SSR stub needed (effect override moved to server setup).
JS tests: 1582/1585 (3 VM closure interop remain)

- signals.sx: guard effect body with (when (client?) ...) so effects
are no-op during SSR — only 2 stubs needed (effect, register-in-scope)
- sx_primitives.ml: add resource SSR stub (returns signal {loading: true}),
remove 27 unnecessary browser primitive stubs
- sx_server.ml: native component-source that looks up Component/Island
from env and pretty-prints the definition (replaces broken Python helper)
- reactive-islands/index.sx: Examples section with all 15 live demos
inline + highlighted source via component-source
- reactive-islands/demo.sx: replace 14 hardcoded highlight strings with
(component-source "~name") calls for always-current source

dom-id returns "" for elements without an id attribute, and "" is
truthy in SX. This caused morph-children to build spurious entries
in old-by-id keyed by "", then match unrelated children via the
empty key — advancing oi past id-keyed children like #main-content
and skipping them in cleanup.
Three changes in morph-children (engine.sx):
- old-by-id reduce: normalize empty dom-id to nil so id-less
elements are excluded from the lookup dict
- match-id binding: normalize empty dom-id to nil so new children
without ids don't spuriously match old children
- Case 2 skip condition: use (not (empty? ...)) instead of bare
(dom-id old-child) to avoid treating "" as a real id

Three bugs in the DOM morph algorithm (web/engine.sx):
1. Empty-id keying: dom-id returns "" (not nil) for elements without an
id attribute, and "" is truthy in SX. Every id-less element was stored
under key "" in old-by-id, causing all new children to match the same
old element via the keyed branch — collapsing all children into one.
Fix: guard with (and id (not (empty? id))) in map building and matching.
2. Cleanup bug: the oi-cursor cleanup (range oi len) removed keyed elements
that were matched and moved from positions >= oi, and failed to remove
unmatched elements at positions < oi. Fix: track consumed indices in a
dict and remove all unconsumed elements regardless of position.
3. Island attr sync: morph-node delegated to morph-island-children without
first syncing the island element's own attributes (e.g. data-sx-state).
Fix: call sync-attrs before morph-island-children.
Also: pass explicit `true` to all dom-clone calls (deep clone parameter).

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.

Reverse hook syncs VM GLOBAL_SET mutations back to global_env so CEK reads
see JIT-written values. Isomorphic nav: store primitives, event-bridge,
client? predicate. Browser JS and bytecode rebuilt.

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).
