feat(tests): add comprehensive happy path tests for session lifecycle
- Implemented session cleanup tests to ensure proper handling of session completions and cleanup operations. - Added session initialization tests to verify session creation and observation queuing on first tool use. - Created session summary tests to validate summary generation from conversation context upon session pause or stop. - Developed integration tests to cover the full observation lifecycle, including context injection, observation queuing, and error recovery. - Introduced reusable mock factories and scenarios for consistent testing across different test files.
