Marketplace-not-found errors now distinguish unreadable registries from hidden registrations.
The marketplace-not-found error now distinguishes three cases instead of always saying "not found": if the marketplace registry couldn't be read, it points to known_marketplaces.json and suggests running /reload-plugins; if the marketplace is registered but hidden (refused, visible in the debug log), it suggests removing and re-adding the marketplace; otherwise it falls back to the old "available marketplaces" message.
