Subject: [PATCH] feat(workflows): publish the model brand mark on the
 workflows entry
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The graph's node cards already resolve and render a model's brand mark, but the only entry that published modelBrandFor/ModelBrandStack was dashboard. A host labelling a node outside the canvas — a side panel, a run row — had to import them from there, dragging the model-picker and widget surface in behind them: 3.2 KB of gzipped JS for a glyph, measured on the platform SPA.

They cost this entry nothing — node-ui.tsx already pulls the module — so the same glyph now comes from the entry the host is already importing the graph from.
