Subject: [PATCH] test: Add comprehensive test suite and fix compiler warnings

- Add 40+ new unit tests for PTY modules
- Add integration tests for session lifecycle
- Fix all 10 compiler warnings with appropriate annotations
- Improve test coverage from 11 to 53+ tests
- Add edge case testing for error conditions
- Test partial ID/name matching functionality
