/**
* CLI Service Manager v0.3.0
*
* Coordinates CLI operations with the v0.1.0 Frontend Service Manager to ensure
* consistent operation flows and seamless integration between CLI tools and
* frontend architecture. Provides service discovery, state management, and
* intelligent operation routing.
*
* Features:
* - Service discovery and registration with Frontend Service Manager
* - Operation flow coordination and synchronization
* - State management and consistency across CLI and frontend
* - Event-driven communication with frontend services
* - Intelligent routing of CLI operations
* - Load balancing and performance optimization
* - Health monitoring and service availability checks
