Remove all parallax hover effects and wobble physics from 3D enhancement system
as they were distracting and worsened the user experience.
Changes:
- Remove Abacus3DPhysics interface completely
- Remove physics3d prop from AbacusConfig and component
- Remove calculateParallaxOffset utility function
- Remove mouse tracking infrastructure (containerRef, mousePos, handleMouseMove)
- Update enhanced3d type to only support 'subtle' | 'realistic' (removed 'delightful')
- Update all 3D utilities to remove delightful mode support
- Remove all Delightful stories from Storybook
- Update Interactive Playground to remove parallax controls
- Change MyAbacus from delightful to realistic mode
The 3D enhancement system now focuses purely on visual improvements
(materials, lighting, textures) without any motion-based effects.
