Intelligent Agent Orchestration Engine for Research-to-Code Automation

This module serves as the core orchestration engine that coordinates multiple specialized
AI agents to automate the complete research-to-code transformation pipeline:

1. Research Analysis Agent - Intelligent content processing and extraction
2. Workspace Infrastructure Agent - Automated environment synthesis
3. Code Architecture Agent - AI-driven design and planning
4. Reference Intelligence Agent - Automated knowledge discovery
5. Repository Acquisition Agent - Intelligent code repository management
6. Codebase Intelligence Agent - Advanced relationship analysis
7. Code Implementation Agent - AI-powered code synthesis

Core Features:
- Multi-agent coordination with intelligent task distribution
- Local environment automation for seamless deployment
- Real-time progress monitoring with comprehensive error handling
- Adaptive workflow optimization based on processing requirements
- Advanced intelligence analysis with configurable performance modes

Architecture:
- Async/await based high-performance agent coordination
- Modular agent design with specialized role separation
- Intelligent resource management and optimization
- Comprehensive logging and monitoring infrastructure
