giles 8d3ab040ef Fix WASM browser: broken links (&rest bytecode) + broken reactive counter (ListRef mutation) ...

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
