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.

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

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

fix: isolate GROQ_API_KEY in test_missing_stt_key test
...
The test was failing because GROQ_API_KEY leaked from the environment.
Now both VOICE_TOOLS_OPENAI_KEY and GROQ_API_KEY are removed to
properly test the "no STT key" scenario.

feat: add voice mode with push-to-talk and TTS output for CLI
...
Implements Issue #314 Phase 2 & 3:
- /voice command to toggle voice mode (on/off/tts/status)
- Ctrl+Space push-to-talk recording via sounddevice
- Whisper STT transcription via existing transcription_tools
- Optional TTS response playback via existing tts_tool
- Visual indicators in prompt (recording/transcribing/voice)
- 21 unit tests, all mocked (no real mic/API)
- Optional deps: sounddevice, numpy (pip install hermes-agent[voice])
