Add comprehensive semantic design token system

Implement complete semantic layer for all design tokens including typography, spacing, motion, colors, borders, shadows, z-index, opacity, and glass effects. Each semantic token maps base design tokens to contextual usage patterns for improved maintainability and developer experience.

Features:
- Complete semantic typography system with font weights, sizes, line heights, and letter spacing
- Comprehensive spacing tokens for components, layouts, and interactions
- Full motion system with durations, easing, transitions, and hover transforms
- Semantic color system with individual access to all Material Design 3 colors
- Border tokens with widths, radius, and styles for all use cases
- Shadow system including standard and AI-themed shadows
- Z-index layering system for proper stacking context
- Opacity tokens for transparency and visibility states
- Glass morphism tokens with blur, opacity, and theming support

All semantic tokens provide direct access to base token values while offering meaningful contextual aliases for common UI patterns.
