⚡ Optimize MicrotubuleTorus rendering with InstancedMesh

[jason420247]

💡 What: Refactored the MicrotubuleTorus component in components/QuantumScene.tsx to use THREE.InstancedMesh instead of individual mesh components.

🎯 Why: Rendering thousands of individual meshes is extremely expensive and causes excessive draw calls. Using InstancedMesh allows the GPU to render all instances in a single draw call per torus, significantly improving performance.

📊 Measured Improvement: The number of draw calls for the two MicrotubuleTorus instances in the QuantumScene (with counts of 360 and 720) is reduced from 1080 to 2. This results in a massive reduction in CPU-to-GPU communication overhead.
