BISAM20andClaude Opus 5 2567f028ef fix: surface newly released models instead of a frozen repo list
The repo list is cached to .repo_cache.json, but list_all_repos() returned
that file whenever it existed, with no expiry. The cache on this machine dated
from 2026-03-22, so nothing released in the following six months appeared at
all — Comfy-Org/Qwen3.8-27B, MoGe, MiniMax-H3, YuE2 and the entire LTX-2.5
family were simply absent. The newest-first sort was working correctly the
whole time; it was sorting stale data. The cache now expires after six hours.

Lightricks becomes a tracked author rather than a single pinned LTX-2.3 repo.
That brings in all 66 of its repos including the 13 LTX-2.5 ones, and means
future LTX releases arrive without another code change. The existing "ltx"
taxonomy keyword already tags them as LTX Video.

Rebuilding used to call repo_info() once per pinned repo, roughly 180
sequential round trips, which made a refresh slow enough that expiring the
cache automatically would have been painful. Pinned repos cluster into about
ten authors, so the rebuild now lists each author once and reads lastModified
from that, six authors in parallel: 314 repos in 8.4s.

Verified against HuggingFace: list sorted newest-first end to end, top entry
Comfy-Org/Qwen3.8-27B (2026-09-18), all 13 LTX-2.5 repos present and badged.
