Audit found three leaks:
1. explore-view: loadThumbnails() and loadArtistImages() fired on
library search results. These call GetThumbnails (Wails RPC to
Cover Art Archive proxy) and GetArtistImageURL (MB/Wikidata).
Now skipped in library-only mode — library results already have
local cover art and artist images from the library store.
2. explore-album-details: always called LookupReleaseGroup (MB) and
BrowseReleases (MB) regardless of mode. Now skips both in
library-only mode — shows only cache-hydrated header with no
version selector or track listing.
3. explore-artist-details was already correct — the library-only
branch skips all external calls.
