Summary

• Route .usd, .usda, .usdc, .usdz through Three.js USDLoader in the offscreen modelThumbnailer so grid tiles get rendered thumbnails alongside glTF/FBX/OBJ/STL/PLY.
• Wire USD into ModelPreview so the asset detail page shows the interactive 3D viewer for USD assets.
• Backend thumbnails.rs adds USD extensions to MODEL_FORMATS (cache lookup only — generation stays on the frontend, same pattern as the existing renderable model formats).

Test plan

• make typecheck
• make lint
• cargo check
• Manual: scan a folder of USD assets, confirm grid thumbnails render and detail-page viewer loads
