Subject: [PATCH] modal: pin transformers to released >=5.8.0 (no floating @
 main)

Floating @ main let a later main commit hang generate() (the other agent's
deadlock). The local box runs 5.8.0.dev0; uv.lock pins the exact commit, the
image uses the released 5.8.0 wheel of the same line. Qwen3-4B needs no
main-only feature.
