refactor: restructure channel gateway and chat module architecture

- Refactor channel adapters (feishu, telegram, local) with enhanced descriptor and config
- Restructure channel manager, service, types, and outbound messaging
- Simplify chat module by removing normalize.go and chat.go, consolidating into resolver and types
- Update router channel handlers and tests
- Sync swagger documentation

docs/swagger.yaml
