…da timeouts This commit introduces batch processing for the crawl-based broken internal links detection to prevent AWS Lambda 15-minute timeout issues on sites with 100+ pages. Key Changes: - **Batch Processing**: Split crawl detection into batches of 30 pages per Lambda invocation - **S3 State Management**: Store batch results and URL caches in S3 for persistence across invocations - **SQS Continuation**: Chain Lambda invocations via SQS messages for seamless batch processing - **Timeout Handling**: Detect and handle HTTP request timeouts gracefully (skip GET fallback on HEAD timeout) - **Increased Capacity**: Raise MAX_URLS_TO_PROCESS from 100 to 500 to support larger audits - **100% Test Coverage**: Comprehensive test suite covering all batching logic and edge cases Architecture: - `batch-state.js`: S3-based state management utilities - `crawl-detection.js`: Batch processing logic with URL caching - `handler.js`: Batch orchestration with SQS self-looping - `helpers.js`: Enhanced timeout detection for link validation Testing: - Added batch-state.test.js for S3 state management tests - Added crawl-detection.test.js for batch processing tests - Updated handler.test.js and helpers.test.js for full coverage - All tests passing with 100% line and branch coverage This implementation ensures audits complete successfully even for large sites (500+ pages) by processing them in manageable batches across multiple Lambda invocations, with each invocation staying well under the 15-minute timeout limit.

…da timeouts - Implements S3-based batch state management to handle large page sets - Adds SQS self-looping for continuation across multiple Lambda invocations - Processes 30 pages per batch to prevent 15-minute Lambda timeout - Increases MAX_URLS_TO_PROCESS from 100 to 500 - Reuses broken/working URL caches across batches for efficiency - Optimizes HTTP request timeouts (skips redundant GET after HEAD timeout) - Enables scraping cache by default (removed allowCache: false) - Adds deployment verification logs to confirm batching code is active - Achieves 100% test coverage for all internal-links modules
