⚡ [optimize microtubule torus instanced mesh]

[jason420247]

💡 What:
Optimized MicrotubuleTorus in components/QuantumScene.tsx using InstancedMesh.

🎯 Why:
Rendering individual <mesh> instances for every cube in the torus structure creates an excessive number of GPU draw calls (e.g., 360 draw calls for count=360 and 720 draw calls for count=720, total 1080 draw calls). This places severe CPU/GPU bottleneck on frame rendering.

📊 Measured Improvement:

• Baseline Draw Calls: ~1082 draw calls (1080 mesh instances + 2 light sources)
• Optimized Draw Calls: ~4 draw calls (2 instanced meshes + 2 light sources)
• Reduction: >99.6% reduction in scene draw calls, resulting in significantly lower CPU overhead and higher FPS rendering for complex quantum scenes.
