Fix type errors and linting issues
- Fix type annotation errors in transport_registry.py and __init__.py - Fix line length violations in test files (E501 errors) - Fix missing return type annotations - Fix cryptography NameAttribute type errors with type: ignore - Fix ExceptionGroup import for cross-version compatibility - Fix test failure in test_wss_listen_without_tls_config by handling ExceptionGroup - Fix len() calls with None arguments in test_tcp_data_transfer.py - Fix missing attribute access errors on interface types - Fix boolean type expectation errors in test_js_ws_ping.py - Fix nursery context manager type errors All tests now pass and linting is clean.

3. Accumulates multiple WebSocket messages if needed to satisfy the request
