/**
 * Integration tests for TestDataArchitectAgent (Squad 3 - P1 Optimization)
 * Tests real-world scenarios with EventBus and MemoryManager
 *
 * Key Features:
 * - Schema introspection (PostgreSQL, MySQL, MongoDB)
 * - Bulk data generation (10,000+ records/second)
 * - Referential integrity preservation
 * - PII anonymization (GDPR compliance)
 * - Realistic data patterns
 * - Coordination with TestGeneratorAgent
