feat(voice): silence beeps, skip tool markers in TTS, add --yolo

- Mute Android notification stream around SpeechRecognizer to suppress beeps
- Extend speech silence timeouts (3s complete, 10s minimum)
- Remove redundant PlayChime() from conversation loop restarts
- Add IsToolProgressLine() filter: skip Copilot CLI tool markers (spinners,
  fold summaries, shell commands, indented output) during text-to-speech
- Markdown rendering for assistant bubbles, Pause/Stop on same row
- Submodule: add --yolo flag to Copilot CLI invocations
