hailin 55b983a950 feat(it0_app): add WhatsApp-style voice message with async agent interrupt
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
