New VoiceMicButton widget (press-and-hold to record, release to send):
- Records audio to a temp .m4a file via the `record` package
- Slide-up gesture cancels recording without sending
- Pulsing red mic icon + "松开发送/松开取消" feedback during recording
New flow for voice messages:
1. Temp "🎤 识别中..." bubble shown immediately
2. Audio uploaded to POST /api/v1/agent/sessions/:id/voice-message
(multipart/form-data; backend runs Whisper STT)
3. Placeholder replaced with real transcript
4. WS stream subscribed via new subscribeExistingTask() to receive
agent's streaming response — same pipeline as text chat
Voice messages act as async interrupts: if the agent is mid-task the
backend hard-cancels it before processing the new voice command,
so whoever presses the mic button always takes priority.
Files changed:
chat_remote_datasource.dart — sendVoiceMessage() multipart upload
chat_repository.dart — subscribeExistingTask() interface method
chat_repository_impl.dart — implement subscribeExistingTask(); fix
sendVoiceMessage() stub
chat_providers.dart — ChatNotifier.sendVoiceMessage()
voice_mic_button.dart — NEW press-and-hold recording widget
chat_page.dart — mic button added to input area
