v0.3.1

CLI ergonomics round.

New

• -c and -d combinable: target folder (created if missing) with explicit categories; error only when no categories exist anywhere
• category descriptions in -c: invoice:bills and payment requests — included in the classification prompt; double-quoted descriptions may contain commas
• bare filename passed as a weak classification hint (content stays primary)

Changed

• --backend and --min-confidence moved to advanced options (--help-all)
• uncertain files: inline marker + end recap with top-2 categories and probabilities
