🔌 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
