Add broadcast_interruption() to FrameProcessor

Browse Source 
Replace the round-trip push_interruption_task_frame_and_wait() mechanism
with broadcast_interruption(), which pushes an InterruptionFrame both
upstream and downstream directly from the calling processor.

This eliminates race conditions (transcription arriving before the
InterruptionFrame comes back), swallowed-event timeouts (frame blocked
before reaching the sink), and the complexity of _wait_for_interruption
flag / queue bypass / frame.complete() obligations.

- Add broadcast_interruption() to FrameProcessor
- Deprecate push_interruption_task_frame_and_wait() (delegates to new method)
- Remove event field and complete() from InterruptionFrame/InterruptionTaskFrame
- Remove _wait_for_interruption flag and all special-case logic
- Remove frame.complete() calls in stt_mute_filter and llm_response_universal
- Update all 17 call sites to use broadcast_interruption()
- Update tests

- Added `broadcast_interruption()` to `FrameProcessor`. This method pushes an `InterruptionFrame` both upstream and downstream directly from the calling processor, avoiding the round-trip through the pipeline task that `push_interruption_task_frame_and_wait()` required.

- Removed `event` field and `complete()` method from `InterruptionFrame`. Removed `event` field from `InterruptionTaskFrame`. These are no longer needed since `broadcast_interruption()` does not require a round-trip completion signal.

- Deprecated `push_interruption_task_frame_and_wait()` in `FrameProcessor`. Use `broadcast_interruption()` instead. The old method now delegates to `broadcast_interruption()` and logs a deprecation warning.
