b00c5949fc fix: suppress verbose logs during streaming TTS, improve hallucination filter, stop continuous mode on errors 
- Add _vprint() helper to suppress log output when stream_callback is active
- Expand Whisper hallucination filter with multi-language phrases and regex pattern for repetitive text
- Stop continuous voice mode when agent returns a failed result (e.g. 429 rate limit)

a15fa85248 fix: catch OSError on sounddevice import in voice_mode.py

dad865e920 fix: fix silence detection bugs and add Phase 4 voice mode features 
Fix 3 critical bugs in silence detection:
- Micro-pause tolerance now tracks dip duration (not time since speech start)
- Peak RMS check in stop() prevents discarding recordings with real speech
- Reduced min_speech_duration from 0.5s to 0.3s for reliable speech confirmation

Phase 4 features: configurable silence params, visual audio level indicator,
voice system prompt, tool call audio cues, TTS interrupt, continuous mode
auto-restart, interruptable playback via Popen tracking.

32b033c11c feat: add silence filter, hallucination guard, and continuous mode control 
- Skip silent recordings before STT call (RMS check in AudioRecorder.stop)
- Filter known Whisper hallucinations ("Thank you.", "Bye." etc.)
- Continuous mode: Ctrl+R starts loop, Ctrl+R during recording exits it
- Wait for TTS to finish before auto-restart to avoid recording speaker
- Silence timeout increased to 3s for natural pauses
- Tests: hallucination filter, silent recording skip, real speech passthrough

bfd9c97705 feat: add Phase 4 low-latency features for voice mode 
- Audio cues: beep on record start (880Hz), double beep on stop (660Hz)
- Silence detection: auto-stop recording after 3s of silence (RMS-based)
- Continuous mode: auto-restart recording after agent responds
  - Ctrl+R starts continuous mode, Ctrl+R during recording exits it
  - Waits for TTS to finish before restarting to avoid recording speaker
- Tests: 7 new tests for beep generation and silence detection
