* SmartProcess - Intelligent Process Management
*
* Track 2C - System Operations & Output
* Target Token Reduction: 88%+
*
* Provides cross-platform process management with smart caching:
* - Start, stop, monitor processes
* - Resource usage tracking (CPU, memory, handles)
* - Process tree analysis
* - Automatic restart on failure
* - Cross-platform support (Windows/Linux/macOS)
