/**
 * Integration Test Configuration
 *
 * Run with: pnpm test:integration
 *
 * Integration tests:
 * - Located in: test/integration/*.integration.test.ts
 * - Use a REAL database (TimescaleDB/PostgreSQL) for testing
 * - Database is automatically set up, migrated, and cleaned between tests
 * - Longer timeouts for database operations
 * - Run separately from unit tests to keep CI fast
 *
 * Prerequisites:
 * - Docker running with test database container
 * - TEST_DATABASE_URL environment variable (or uses default)
