[Transition] No reduced motion support

## Component
Transition

## Problem
Animations don't respect prefers-reduced-motion media query.

## Suggested Fix
```tsx
const prefersReducedMotion = useMediaQuery('(prefers-reduced-motion: reduce)');

if (prefersReducedMotion || disabled) {
    return children;
}
```

## Impact
Accessibility - Users who prefer reduced motion still see animations
