Fix typecheck errors and improve WebSocket transport implementation

- Fix INotifee interface compliance in WebSocket demo
- Fix handler function signatures to be async (THandler compatibility)
- Fix is_closed method usage with proper type checking
- Fix pytest.raises multiple exception type issue
- Fix line length violations (E501) across multiple files
- Add debugging logging to Noise security module for troubleshooting
- Update WebSocket transport examples and tests
- Improve transport registry error handling
