feat(bridge): add multi-platform bridge — QQ, Telegram, Discord, Webhook

- platform-bridge: unified message model + Adapter interface
- qq/adapter: OBv11 WebSocket protocol with @mention detection
- telegram/discord: stub adapters with send capability
- webhook: HTTP POST receiver for generic webhook integration
- Router: message routing from platform → AI-Core → back
- Group chat rules: 500 char limit, 3s gap, silence keywords
- main.go: conditional adapter loading via env vars
