Two bugs fixed:
1. Links: bytecode compiler doesn't handle &rest params — treats them as
positional, so (first rest) gets a raw string instead of a list.
Replaced &rest with explicit optional params in all bytecode-compiled
web SX files (dom-query, dom-add-listener, browser-push-state, etc.).
The VM already pads missing args with Nil.
2. Reactive counter: signal-remove-sub! used (filter ...) which returns
immutable List, but signal-add-sub! uses (append!) which only mutates
ListRef. Subscribers silently vanished after first effect re-run.
Fixed by adding remove! primitive that mutates ListRef in-place.
Also:
- Added evalVM API to WASM kernel (compile + run through bytecode VM)
- Added scope tracing (scope-push!/pop!/peek/context instrumentation)
- Added Playwright reactive mode for debugging island signal/DOM state
- Replaced cek-call with direct calls in core-signals.sx effect/computed
- Recompiled all 23 bytecode modules

dom-lib and browser-lib were listed in ADAPTER_FILES but never actually
transpiled — their functions only existed as native PLATFORM_*_JS code.
Add them to the build loop so the FFI library wrappers are compiled.
Add hostCall/hostGet/etc. variable aliases for transpiled code, and
console-log to browser.sx for runtime-eval'd SX code.

Introduce 8 irreducible host FFI primitives that replace 40+ native DOM
and browser primitives:
host-global — access global object (window/document)
host-get — read property from host object
host-set! — write property on host object
host-call — call method on host object
host-new — construct host object
host-callback — wrap SX function as host callback
host-typeof — check host object type
host-await — await host promise
All DOM and browser operations are now expressible as SX library
functions built on these 8 primitives:
web/lib/dom.sx — createElement, querySelector, appendChild,
setAttribute, addEventListener, classList, etc.
web/lib/browser.sx — localStorage, history, fetch, setTimeout,
promises, console, matchMedia, etc.
The existing native implementations remain as fallback — the library
versions shadow them in transpiled code. Incremental migration: callers
don't change, only the implementation moves from out-of-band to in-band.
JS 957+1080, Python 744, OCaml 952 — zero regressions.
