feat(session): implement session expiration with configurable timeout (#83)

Browse source 
- Add CLAUDE_SESSION_EXPIRY_HOURS configuration variable (default: 24)
- Add get_session_file_age_hours() helper with cross-platform stat support
- Modify init_claude_session() to check session age and remove expired sessions
- Add --session-expiry CLI flag to configure expiration (positive integers only)
- Update help text with new option and example
- Add 10 new tests for session expiration (TDD approach)

Closes #51

Test count: 276 → 286 (100% pass rate)
