MIESC v4.0.0 - Complete End-to-End Demonstration
Multi-layer Intelligent Evaluation for Smart Contracts

This script demonstrates the complete MIESC pipeline:
1. Adapter registration and validation (25 adapters across 7 layers)
2. Multi-contract analysis
3. Vulnerability detection aggregation
4. Performance metrics and statistics
