feat: voice S2S — faster-whisper STT, Kokoro TTS, PTT overlay
Implements full speech-to-speech pipeline (all 4 phases): Backend (Phase 1): - services/stt.py: lazy WhisperModel singleton, run_in_executor transcription - services/tts.py: lazy KPipeline singleton, WAV synthesis at 24kHz/16-bit - routes/voice.py: /api/voice/status, /voices, /transcribe, /synthesise - config.py: VOICE_ENABLED, STT_BACKEND, STT_MODEL, TTS_BACKEND env vars - app.py: load STT/TTS models at startup when VOICE_ENABLED=true - llm.py: voice_mode + voice_speech_style params inject speak-naturally prefix - generation_task.py: voice_mode passed through from chat route - chat.py: "voice" conversation type allowed + excluded from retention cleanup - pyproject.toml + Dockerfile: faster-whisper, kokoro, soundfile dependencies Frontend (Phases 2–4): - composables/useVoiceRecorder.ts: MediaRecorder PTT wrapper - composables/useVoiceAudio.ts: AudioContext WAV playback wrapper - BriefingView.vue: Listen button (TTS read-aloud), auto-TTS mode, mic PTT - VoiceOverlay.vue: global floating PTT button; creates/reuses voice conv; full record→transcribe→stream→TTS flow; Space bar hold-to-talk via App.vue - SettingsView.vue: Voice tab (status badge, speech style, voice/speed) - App.vue: mounts VoiceOverlay; Space keydown/keyup fires voice:ptt-toggle - api/client.ts: getVoiceStatus, getVoiceList, transcribeAudio, synthesiseSpeech Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
