// HTTP route for manually-pinned launcher shortcuts (collections / feeds).
//
//   GET /api/shortcuts  → { shortcuts }
//   PUT /api/shortcuts  → replace the full list → { shortcuts }
//
// The client owns ordering / add / remove and sends the whole array;
// the server normalises (validate kind, non-empty slug, dedupe on
// `(kind, slug)`, no length cap) before persisting. A single
// replace-endpoint avoids add/remove route sprawl.
