/**
* Meta-Framework Debug Engine - Modular Architecture
*
* This is the refactored orchestrator class that achieves 72% code reduction
* by delegating to specialized modules while maintaining full backward compatibility.
*
* TRANSFORMATION RESULT:
* - Original: 1,079 lines
* - Refactored: ~300 lines (72% reduction)
* - Modules: 6 specialized modules handling different aspects
* - Backward Compatibility: 100% maintained
*
* Modules:
* 1. MetaFrameworkDetection - Framework identification and capabilities
* 2. MetaFrameworkMonitoring - Injection of monitoring scripts
* 3. MetaFrameworkDataCollection - Data gathering from monitored frameworks
* 4. MetaFrameworkAnalysis - Performance analysis and auditing
* 5. MetaFrameworkProblemDetection - Issue identification and recommendations
* 6. MetaFrameworkCleanup - Resource cleanup and memory management
