SDK for HumanBehavior session and event recording

/**
 * AI-Enhanced HumanBehavior SDK Auto-Installation Wizard
 * 
 * This wizard uses AI to intelligently detect frameworks, analyze code patterns,
 * and generate optimal integration code that's both future-proof and backward-compatible.
 * 
 * 🚀 KEY FEATURES:
 * - AI-powered framework detection beyond package.json
 * - Intelligent code pattern analysis
 * - Future-proof integration strategies
 * - Backward compatibility with legacy frameworks
 * - Adaptive code generation for new frameworks
 * - Smart conflict resolution
 * - Learning from user feedback
 * - Centralized AI service (no user API keys required)
