optimize: WeChat channel message handling and error resilience

Browse Source 
- Filter messages by message_type=1 to skip bot echo and prevent loops
- Add voice message support (type=3) with voice-to-text extraction
- Check resend results and re-buffer failed messages to prevent loss
- Handle session expiry (ret=-14) with 30s pause in polling loop
- Use exponential backoff (5s–30s) for network errors instead of fixed 5s
