⚡ Optimize MicrotubuleTorus rendering with InstancedMesh

[jason420247]

💡 What: Refactored the MicrotubuleTorus component in components/QuantumScene.tsx to use THREE.InstancedMesh instead of individual mesh components. A reusable THREE.Object3D is used within the useFrame loop to efficiently update instance matrices.

🎯 Why: Rendering hundreds or thousands of individual meshes (360 and 720 in the current scene) is expensive due to the high number of draw calls. InstancedMesh allows rendering all instances of the same geometry and material in a single draw call.

📊 Measured Improvement: The optimization reduces the number of draw calls from approximately 1080 (360 + 720 individual meshes) to 2 (one for each MicrotubuleTorus instance). This significantly reduces CPU overhead and improves frame rates in complex scenes.
