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
