Initial commit: Linux System Tuning Suite

- Intelligent hardware detection and analysis
- Modular optimization system with profiles
- Automatic tmpfs, zram, and kernel tuning
- Real-time monitoring and health checks
- Support for desktop, gaming, and development workloads
- Safe backup and rollback capabilities
- Systemd integration for persistent optimizations
