rshtirmer 707206cc9f feat: add GLB optimization pipeline for web-ready 3D assets ...

Meshy AI generates raw GLBs (1-25MB) with uncompressed textures and high
polycounts. New optimize-glb.mjs script automatically reduces file sizes
by 80-95% via texture resize, WebP conversion, and meshopt compression.

- Add scripts/optimize-glb.mjs (standalone, zero-dep, uses npx gltf-transform)
- Auto-optimize after every GLB download in meshy-generate.mjs and find-3d-asset.mjs
- Add MeshoptDecoder to AssetLoader.js template for runtime decompression
- Lower default polycount from 30,000 to 10,000 for game-ready topology
- Add --no-optimize flag to skip optimization when needed
