- Added ObjCExceptionCatcher to handle Objective-C exceptions during AVAudioNode tap installation, preventing crashes when the audio subsystem is not fully initialized.
- Introduced a 0.5s delay before starting the voice wake runtime to ensure the audio subsystem is ready, reducing the risk of AVAudioEngine errors.
- Updated VoiceWakeRuntime to utilize the new exception catcher and implemented retry logic for starting the runtime with exponential backoff.
This enhances the stability of the voice wake feature during app launch.
- Keep the chosen mic label visible when it disconnects and show a disconnected hint while falling back to system default.
- Avoid clearing the preferred mic on device changes so it auto-restores when available.
- Add audio input change and default-input logs in voice wake runtime/tester/meter to debug routing.
Why: voice wake tests often delivered partial/final transcripts without reliable word timings, so trigger matching failed, timeouts overwrote detections, and test runs/mic capture kept running after UI changes.
What: add text-only/prefix fallback and silence-based detection in the test flow, stop/clean up any prior test, cancel timeout on detection/stop, and tear down meter/test when the Voice Wake tab is inactive. Runtime detection now falls back on final text-only matches when timing is missing. UI state now reflects finalizing and prevents hanging tests.
