[PERF] Develop Resource Guard for Real-time Performance Monitoring

[Awambeng]

Ensure security tools don't slow down the computer by monitoring and optimizing resource usage.

Requirements:

• Monitor system-wide CPU and Memory usage in real-time.
• Identify "greedy" processes exceeding defined thresholds.
• [Linux/macOS] Implement "Soft-Fix" by lowering process priority using renice.
• Notify the user when an optimization has been applied.

Dependencies:

• [HARDENING] Implement Zero-Trust mTLS and Secret Management #109: Performance data and optimization commands must be securely transmitted.
