Replace the naive Vec<SignalType> signal queue in HostState with the proper SignalsHost implementation from US-109. This enables interest registration, bounded queueing (capacity 16), and signal filtering through the WIT boundary. Update all unit tests and integration tests across warpgrid-host and warp-runtime to use the new `signals: SignalsHost::new()` field. Fix pre-existing `wat` workspace dependency issue. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Create a no_std guest component that exercises the signals WIT interface: - register-terminate/hangup/interrupt: register interest via on-signal - poll: dequeue signals and return their name as a string The fixture follows the same pattern as fs-shim-guest, using wit-bindgen 0.42 and targeting wasm32-unknown-unknown. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Add 5 integration tests exercising the full WIT boundary for signal handling through a real Wasmtime engine: - AC #1: register → deliver → poll round-trip - AC #2: empty queue returns None - AC #3: queue bounding (20 delivered, 16 retrievable) - AC #4: signal filtering (unregistered types ignored) - Extra: multi-type FIFO ordering Each test compiles and instantiates the signal-shim-guest Wasm component, calls exported functions through the component model, and verifies host-side SignalsHost behavior end-to-end.

PRs #101 (signals) and #104 (threading) introduced a merge conflict that GitHub's auto-merge didn't catch: HostState's `signal_queue: Vec<_>` field was renamed to `signals: SignalsHost` by #101, but #104's tests still used the old field name, preventing compilation.
