- license_rules table (name -> commercial); licenses auto-register on
import with a best-effort seed, overridable in Settings (applies the
choice to every model with that license)
- resolveCommercial() replaces ad-hoc inferCommercial across import/refresh
- GET/PUT /api/licenses; "License types" section in Settings
- Fix CC short codes: BY / BY-SA / BY-ND now classed sellable (MakerWorld
stores e.g. "BY-SA"); NC variants stay non-commercial
