feat: implement production-ready MUC operations and comprehensive testing

- Implement proper XMPP MUC operations using mellium.im/xmpp/muc package
- Add session readiness checking to prevent blocking on room joins
- Create comprehensive bridge manager architecture with lifecycle management
- Add complete channel mapping functionality with KV store persistence
- Remove defensive logger nil checks as requested by user
- Enhance XMPP client doctor with MUC testing (join/wait/leave workflow)
- Add detailed dev server documentation for test room creation
- Implement timeout protection for all MUC operations
- Add proper error handling with fmt.Errorf instead of pkg/errors
- Successfully tested: MUC join in ~21ms, 5s wait, clean leave operation

#### Test MUC Operations
To test Multi-User Chat room operations (requires the test room created above):
```bash
# Test MUC room join/leave operations
go run cmd/xmpp-client-doctor/main.go --test-muc
```
This will test joining the `test1@conference.localhost` room, waiting 5 seconds, and then leaving.
