I've added a shape selector control that lets you transform the particle system into different 3D shapes. The new control panel includes six shape options: Plane (original flat grid), Orb (spherical), Envelope (mail envelope outline), Cube, Cylinder, and Torus. Each shape maintains all the wave animations and color transitions, so you'll see the white particles morphing into orange and blue at the peaks regardless of which shape you choose. The shapes are positioned at the top of the controls for easy access.

I've completely transformed the particle system so particles now fully morph into each shape with unique, shape-specific behaviors and controls. The plane has wave animations, the orb rotates and pulses, the envelope has an animated folding flap, the cube rotates on all axes with expansion, the cylinder spins with twist and wave effects, and the torus rotates with twist and pulse. Each shape now has its own dedicated control panel that appears when selected, giving you precise control over that shape's unique animations.

Fixed the dependency array issue by including all the params properties that are used within the useMemo hook, particularly those passed to getShapePosition which uses different params depending on the selected shape.

Fixed the lint error by simplifying the useMemo dependency array to just use params instead of listing all individual properties. This is cleaner and resolves the exhaustive dependencies warning.
