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.

-      'v0.27.1:0 — bug fix: "Download a new model" now works on its own. The downloader on the Spark relies on a helper tool (uvx, part of Astral\'s uv) that the standard installer places under your home directory in ~/.local/bin. Spark Control runs downloads over an automated SSH session that wasn\'t looking there, so a download failed immediately with "uvx: command not found" even though the tool was installed. Spark Control now includes ~/.local/bin on the path when it runs a download, so the Download button works with no manual setup. No other changes; the /v1 proxy, swap, and coordination APIs are unchanged.',
+      'v0.27.2:0 — vision support is now visible and testable in the dashboard. (1) Qwen3.6-35B-A3B is a vision model (it reads images, including OCR), but its card was mislabelled text-only — it now shows the "vision" badge. (2) NEW: a "Vision check" button appears on the running model\'s card when it supports images. Upload a picture (e.g. a business card) with a prompt and see what the model reads back, right in the dashboard — confirmed reading a business card cleanly on the Qwen3.6 vision model. It uses the same on-LAN /v1 endpoint your apps already use, so nothing leaves your network. No consumer-API changes; the /v1 proxy, swap, and coordination APIs are unchanged.',
