/**
 * PHASE 2 TODO: Comprehensive API route integration tests
 *
 * The following tests should be implemented in Phase 2 with Miniflare + MSW:
 *
 * 1. GET /health - Database connectivity test
 * 2. GET /api/stats - Database statistics
 * 3. GET /api/search - ISBN, title, author search
 * 4. POST /api/enrich/batch-direct - Batch enrichment
 * 5. POST /covers/:isbn/process - Cover processing
 * 6. GET /covers/:isbn/:size - Cover serving
 * 7. GET /api/quota/status - Quota status
 * 8. POST /api/authors/enrich-bibliography - Author bibliography
 *
 * Testing approach:
 * - Use Miniflare for Workers runtime simulation
 * - Use MSW for external API mocking (ISBNdb, Google Books, OpenLibrary)
 * - Test zod schema validation
 * - Test error handling (4xx, 5xx)
 * - Test authentication/authorization
