Adds the surface AssetMenu needs to live in the lib without importing
artcraft-host APIs:
- listUserMediaFiles / listFeaturedMediaFiles — paginated media
listings backed by MediaFilesApi
- getCdnUrl — wraps host BucketConfig for thumbnail composition
- showToast — wraps host addToast / react-hot-toast pipeline
useTauriPageSceneAdapter wires all four to the existing artcraft host
plumbing (~/Classes/ApiManager/MediaFilesApi, ~/api/BucketConfig,
~/signals/addToast). No call sites yet — the AssetMenu file move that
consumes these is the next step.
Typecheck stays at 58.
