/**
* CLI Command Router v0.3.0
*
* Provides intelligent command routing, processing, and integration with the
* Intelligent Task Processor for enhanced CLI capabilities and 100% backward
* compatibility. Routes commands through the new architecture while maintaining
* complete compatibility with existing CLI syntax.
*
* Features:
* - Intelligent command parsing and routing
* - Integration with Intelligent Task Processor for enhanced capabilities
* - Command validation and enrichment
* - Batch operation support and optimization
* - Streaming operations for large datasets
* - Command history and analytics
* - Backward compatibility with all existing CLI commands
