- Complete ChannelPlugin implementation for QQ messaging
- WebSocket client with auto-reconnect and heartbeat
- Support private chat and group messages
- OneBot v11 API wrapper (send, receive, group management)
- Onboarding wizard for CLI configuration
- Multi-account support
- 156 unit tests (accounts, client, api, send, monitor, normalize, connection)
