Complete WebSocket transport implementation with TLS support
- Add TLS configuration support to new_host and new_swarm functions - Fix WebSocket transport tests (test_wss_host_pair_data_exchange, test_wss_listen_without_tls_config) - Integrate TLS configuration with transport registry for proper WebSocket WSS support - Move debug files to downloads directory for future reference - All 47 WebSocket tests now passing including WSS functionality - Maintain backward compatibility with existing code - Resolve all type checking and linting issues
