The manage-marketplaces screen now suggests marketplaces synced from claude.ai that you haven't added yet.
The manage-marketplaces screen now fetches a synced list of marketplaces from a claude.ai-linked plugin sync feature and shows ones not yet added alongside the user's installed marketplaces, letting them pick one to add directly. A 'browse-only' subset of these is tracked separately. Previously the screen only showed already-configured marketplaces.
