feat: SimView on the wasm engine - #37

Conversation
`ui/view.ts` and `ui/framelog.ts` now drive `comline-simulator` (Rust → WASM) instead of the TypeScript `Wires` / `Session` / `Clock` / `Recorder`. - `createSim` holds a `Sim`, mirrors `sim.session_json()` for rendering, and drives it: a call is `sim.call()` → advance the clock (`run` in real mode, `step` / `advance` in stepped) → poll `sim.result()`. - the frame log polls `sim.frames()` / `sim.describe_frame()` after each advance instead of subscribing to a `Tap`; `poll()` appends new rows. - the play loop is a `setInterval` calling `sim.advance(32 × speed)`. - record / replay: `sim.record_start` / `record_stop` / `load_replay` (input capture is automatic in the facade); `Recorder` gone from the view. - behaviours: `sim.behavior_catalog()` for the picker; the `script` kind is filtered out until the scripted wasm is lazy-loaded. - version-skew resync: `sim.resync_instance()`. `shape.ts` and `argsform.ts` are unchanged — pure form-building over the `describe_project` JSON. The `SimView` interface, DOM structure and CSS classes are unchanged; the app builds, both wasms bundle (editor 932 KB + sim 523 KB). Two `view.test.ts` cases rewritten for the discrete-event clock: "idle separator" is now a *virtual*-time gap (a `delay` behaviour), and the stepped-clock test steps per event (request delivery, then the delayed response) rather than once. 44 tests green. The dead TS engine modules + their tests + the drift guard go in the next PR.
