Implement POST /library/scan endpoint that accepts multipart image uploads and extracts metadata (label name, catalog number, UPC, DJ review text) via Google Gemini Flash vision API. Each extracted field includes a confidence score. Add POST /library/scan/upc-lookup endpoint for Discogs barcode search. New scanner service follows singleton pattern from parser.service.ts. Multer middleware handles in-memory image buffering with 10MB limit.
