1. Unit Tests: Add tests for subsystems 03-09 (currently only 01-02 have tests)
2. Real Networking: Replace NetworkDiagnostics stub with actual networking library (e.g., Asio)
3. ML Models: Add trained models to AutomatedAnalyzer for classification
4. GUI Tools: Create visual tools for analyzing traces, profiles, and recordings
5. CI/CD: Add GitHub Actions workflow for automated builds
6. Benchmarks: Add performance benchmarks for each subsystem
