Refactor tests and add integration tests for runtime module

- Added integration tests for the runtime module covering subprocess lifecycle, concurrency, and real-world scenarios in `test_runtime_integration.py`.
- Updated existing test files to include a blank line after module docstrings for consistency.
- Enhanced `test_protocol_legacy_adapter.py` with additional assertions for message output.
- Modified `test_transport.py` to use concrete transport implementations for abstract method tests.
- Improved test cases for handling timeouts and remote handler tracking in `test_timeout_handling.py` and `test_peer_remote_handlers.py`.
