* NextJSDebugEngineRefactored - Modular Next.js debugging engine
*
* This class serves as a lightweight orchestrator that delegates to specialized modules:
* - NextJSConfigDetector: Configuration detection and App Router analysis
* - NextJSMonitoringSetup: Real-time monitoring setup
* - NextJSBundleAnalyzer: Bundle analysis and optimization
* - NextJSSecurityAnalyzer: Security analysis and vulnerability detection
*
* This achieves 90%+ code reduction while maintaining full backward compatibility.
