- Implemented supplier scoring logic in `supplier-scoring.ts` with functions to compute demand score, competition penalty, and overall supplier product score. - Created unit tests for supplier scoring in `supplier-scoring.test.ts` to validate scoring logic against various scenarios. - Developed UPC file analysis tool in `upc-file-analysis.ts` to process UPCs in batches, fetch product data from Keepa and SP-API, and generate supplier results. - Added UPC input reading functionality in `upc-file-reader.ts` to handle XLSX and XLS files, including validation for UPC formats. - Introduced a command-line tool in `upc-lookup.ts` for looking up UPCs and displaying detailed results or mappings to ASINs. - Enhanced error handling and logging throughout the new modules for better traceability and user feedback.
