- 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`.
- Implement tests for HandlerDispatcher in `tests_v4/test_handler_dispatcher.py`, covering initialization, invocation, cancellation, argument building, result consumption, error handling, and handler execution.
- Introduce tests for Plugin loading functionalities in `tests_v4/test_loader.py`, including plugin specification, discovery, environment management, and loading components and handlers.
- Created `test_protocol_messages.py` to cover tests for protocol message models including ErrorPayload, PeerInfo, InitializeMessage, ResultMessage, InvokeMessage, EventMessage, CancelMessage, and the parse_message function.
- Implemented validation tests to ensure required fields and serialization behavior.
- Added `test_transport.py` to test the Transport base class and its implementations: StdioTransport and WebSocketTransport.
- Included tests for lifecycle methods, message handling, and error conditions in transport classes.
- Added internal capability for handler invocation in SupervisorRuntime.
- Implemented lifecycle hooks (on_start, on_stop) in Star class and PluginWorkerRuntime.
- Updated CapabilityRouter to support request_id in call and stream handlers.
- Refactored message handling in PeerRuntime to include request_id.
- Introduced tests for API contract, legacy adapter, and migration scenarios.
- Improved WebSocketServerTransport to manage connection state more effectively.
- Enhanced plugin loading and discovery to maintain compatibility with legacy systems.
- Added Peer class for managing peer-to-peer communication, including initialization, invocation, and cancellation of requests.
- Introduced Transport abstract base class with StdioTransport and WebSocketTransport implementations for message handling.
- Created Star class for error handling in event-driven architecture.
- Developed MemoryTransport for testing purposes, allowing in-memory communication between peers.
- Implemented unit tests for Peer functionality, protocol message parsing, and runtime integration with plugins.
- Established entry point tests to ensure package import and command-line interface functionality.
