## 🔌 Personal WeChat Channel

Added personal WeChat (`weixin`) channel — the most important update in this release. Simply scan a QR code to connect CowAgent to your personal WeChat account, with support for:

- **Messaging**: Send and receive text, image, file, and video messages; receive voice messages
- **QR Code Login**: QR code displayed in terminal, scan with WeChat to log in; auto-refresh on expiry
- **Credential Persistence**: Login credentials saved to `~/.weixin_cow_credentials.json` automatically, no re-scan needed on restart
- **Session Auto-Reconnect**: Automatically clears expired credentials and re-initiates QR code login
- **Web Console Integration**: Add WeChat channel from the Web Console with synchronized QR code login flow
- **Docker & Script Support**: Both `run.sh` and `docker-compose.yml` now support the WeChat channel
