docs: Update CLAUDE.md to reflect Phase 2 completion

**Updates:**
- Project status: v2.0.1 Phase 2 Security Remediation Complete
- Architecture overview: Updated to show ActionExecutor in daemon layer
- Test counts: 449 total workspace tests (45 core + 32 daemon + 26 GUI)
- Added midimon-gui as 4th crate in workspace structure
- Updated architecture diagram to show action execution flow

**Phase 2 Achievements:**
- Core library is now truly UI-independent
- Action execution isolated in daemon layer
- Security enhancements: path validation, input sanitization
- New features: Repeat action delay, conditional actions
- Comprehensive documentation and guides

**Next Phase:**
Phase 3 - GUI Polish & User Testing
