Deluan 04d5a55657 perf(artwork): stop reading and hashing disc art on every request
The resize-cache key was the content hash, which cannot be computed
without reading the file, so a warm cache never prevented the I/O: every
sized disc request read up to 20MB and hashed it before the lookup. The
legacy reader keyed on the id and the album's mtime and touched the file
only on a miss.

Disc art has no state row and therefore no stored hash, so the key is
that same identity — id, album mtime, DiscArtPriority — and the
selection chain now runs only when the cache misses. Full-size requests
stream the source instead of buffering and hashing it.

This matters more now that single-disc albums keep running the disc
chain, which puts every disc-tagged track without embedded art on this
path.
