Catalog feed

Not in this version. What exists is the listing draft on each item, with every fact resting on a confirmed field, the disclosures the rules append, and the handoff to the Marketplace create page (Marketplace handoff). A catalog export would take the same drafts and write them in a product feed's columns; nothing of that is built, and no catalog id or token is read by the service. It stays under Next steps with the other channels.
