T3 Code resolves a repository icon from t3.json's iconPath, falling back to
well-known locations such as assets/icon.png. Neither resolved in this repo,
so it showed the default folder icon in the T3 Code sidebar.
The icon reuses the canonical Silo mark unchanged over a navy backdrop,
so the Silo repos stay distinguishable at the ~14px the sidebar renders.
