feat(channels): wire TTS voice reply into web adapter (#1347)#1351
Conversation
Mirrors the Telegram adapter's voice flow: track voice sessions, buffer text by sentence, synthesize via TTS, send audio_delta events. - Add `AudioDelta` and `AudioDone` WebSocket event types - Add `voice_reply` field to inbound WebSocket payload - Add `tts_service` and `voice_session_keys` to WebAdapter - Buffer text deltas at sentence boundaries, synthesize via TTS - Broadcast base64-encoded audio chunks as `audio_delta` events - Graceful degradation: TTS failure logs warning, text stream unaffected - Derive `Clone` on `TtsService` (symmetric with `SttService`) - Wire `tts_service` to WebAdapter in app startup Closes #1347 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
