Description

PruneAssets worker (lib/music_library/worker/prune_assets.ex:16-35) builds Ecto queries and calls Repo.delete_all directly, violating the convention that workers are thin wrappers delegating to context modules. All other workers delegate to context functions. This logic should live in MusicLibrary.Assets.

Expected behavior

Extract the query and deletion into an Assets.prune_unreferenced/0 context function, and have the worker call it.
