Export published CDN links

Returns the same clean hosted-link JSON shown in the collection page Get Links export modal. This endpoint is built from published CDN assets, not raw item types, so pose/image items with attached video loops are included. Includes image sticker URL arrays, animated_stickers grouped by sticker ID with telegram, whatsapp, wechat and discord URL keys in formats, and complete cursor-follower interactions with nine WebP frame URLs and a JSON manifest URL. Only completed, non-archived hosted assets are included. Create cursor followers with POST /v1/collections/{id}/interactive. Use the raw items and assets endpoints for IDs, prompts, metadata, and status checks. No credit cost.
