/**
 * Jest config for migration tests using testcontainers.
 * Migration tests must run sequentially (maxWorkers: 1) because they:
 * - Share the same database instance
 * - Perform rollbacks that affect subsequent tests
 * - Clear and reinitialize the database in beforeEach hooks
 *
 * Usage: pnpm test:postgres:migrations:tc
