Two background fills start inside open() with no caller input, through the
shared pools (#45) at background priority, so on-demand work always preempts
them. Thumbnails: every file newest first until all are on disk, sharing the
thumbnail pool with thumbnails.ensure. Originals: the pinned set — the
favorites album, then the latest-week window ending at the newest file —
through the content pool. The pinned set is the eviction predicate (#47), so a
pinned original is never evicted and a file that leaves the set (favorite
removed or window moved on a later refresh) becomes an ordinary, evictable
original. A cached file costs one map lookup and no fetch; each refresh re-kicks
the fills to pick up new files and retry failures. Progress via open()
onProgress and status() (thumbnailsCached/Total, originalsCached/Pinned).
Model: opus-4-8
Adds the on-disk content and thumbnail cache keyed by fileID: originals/ and thumbnails/ under cacheDirectory, present-means-complete (streaming atomic rename), orphan temp reaping on open. Photo.original/thumbnail return a cached path with no network when present, else fetch through the shared request pool; thumbnails.ensure drives the thumbnail pool with priority, dedup and AbortSignal. One shared RequestPools set serves both the ML fetch and the content cache. Content-hash integrity is deferred (#68); authenticated streaming decrypt guarantees integrity now.
