The cached gallery listing refreshed each entry's installed flag with
one os.Stat per entry, under the cache's global write lock. A gallery
holds about 1,900 entries. On a models directory on SMB, one refresh
took about 14s. The listing and every row's VRAM estimate run this
refresh, and the lock serialized them, so the models page took
minutes to load.
The installed check now lists the models directory once and looks up
each entry in that listing. On the same SMB share the listing takes
about 75ms. The answers match os.Stat: a symlink counts only when its
target exists, and names with a path separator still use os.Stat. The
listing runs before the lock is taken, so the lock covers only the
flag updates.
Concurrent callers on a cold cache now share one upstream load. Before
this, each caller fetched the gallery index and the configs itself.
