/**
 * RuVector GNN Self-Learning Validation Script
 * Phase 0.5.4: End-to-End Integration Testing
 *
 * This script validates that GNN self-learning is working correctly:
 * 1. Connects to RuVector Docker container
 * 2. Stores patterns with learning enabled
 * 3. Queries with GNN-enhanced search
 * 4. Validates cache hit/miss behavior
 * 5. Tests LoRA learning triggers
 * 6. Verifies EWC++ anti-forgetting
 *
 * Usage:
 *   npx tsx scripts/validate-ruvector-gnn.ts [--url=http://localhost:8080]
