Details

Re-implement InstancedMesh optimizations from reference/v2-modular into
the v0-golden monolithic app.js:

- Portal tori: 3 individual MeshStandardMaterial Meshes → 1 InstancedMesh
  with per-instance colors (AdditiveBlending). Reduces 3 draw calls to 1.
- Runestones: 5 individual MeshStandardMaterial Meshes (each fetched via
  scene.getObjectByName per frame) → 1 InstancedMesh. Reduces 5 draw calls
  to 1 and eliminates 5 scene traversals per frame.
- Raycasting updated to use intersectObject(portalRingIM) with instanceId.
- Animation loop updated to write instance matrices via _imDummy (no
  per-frame Object3D allocation).

Fixes #482
