Normalize product names and suppliers from spreadsheets, paste, or workspace files for EPD matching.
Ingests a product list from an xlsx spreadsheet, pasted pipe- or tab-delimited text, or a workspace glob of JSON/xlsx files. Strips dimensional suffixes (100mm, 1200x600, 4" x 8") from product names without inventing new names, slugifies supplier keys, and writes epd-products.json with normalized products plus issues for rows missing a name.
