v0.27.2:0 - vision check tool + mark Qwen3.6 vision-capable

Qwen3.6-35B-A3B is multimodal (vision tower on disk) but was labelled
text-only. Mark it [vision, reasoning] and add a 'Vision check' button on
the running vision-capable card: upload an image + prompt -> existing /v1
passthrough proxy -> show the model's text. Confirmed 7/7 fields on a
business card. Records the Gemma-4-26B deferral + research findings.
