⚡ Optimize MicrotubuleTorus rendering with InstancedMesh

[jason420247]

💡 What:
Refactored the MicrotubuleTorus component in components/QuantumScene.tsx to use THREE.InstancedMesh instead of individual mesh components. The implementation uses a useMemo'd THREE.Object3D for efficient matrix updates within the useFrame animation loop and includes key={count} to handle dynamic instance count changes safely.

🎯 Why:
The previous implementation rendered thousands of individual meshes (360 + 720 = 1080), resulting in excessive draw calls and significant CPU overhead during React reconciliation and Three.js scene graph traversal. Using InstancedMesh allows the GPU to render all instances in a single draw call per torus.

📊 Measured Improvement:

• Draw Calls: Reduced from 1,080 to 2 for the toruses.
• CPU Efficiency: Eliminated the creation and per-frame update of 1,080 separate React components.
• Memory Hygiene: Used a reusable Object3D instance to minimize garbage collection during the animation loop.
• Visual Stability: Added frustumCulled={false} to prevent flickering during complex animations.
