feat(react): add ScrollNumber component and enhance Badge with scroll animation

[wangdicoder]

Summary

• Add new ScrollNumber component with animated digit transitions using shortest-path scrolling across the 0/9 boundary
• Integrate ScrollNumber into Badge so count changes animate smoothly with a bounce easing effect
• Support title, prefix, suffix, precision, group separator, custom duration, and valueStyle
• Right-keyed digit elements so adding/removing leading digits doesn't trigger unwanted scroll animations

Release

• Bump type: minor
• Affected packages: @tiny-design/react (fixed group will also bump @tiny-design/tokens and @tiny-design/icons)

Test plan

• Verify ScrollNumber renders correctly with various values (integers, decimals, negative numbers)
• Verify digit transitions take the shortest path (e.g. 9→0 scrolls forward by 1, not backward by 9)
• Verify new digits appear instantly when digit count increases (e.g. 9→10 shows "1" immediately)
• Verify Badge count changes animate smoothly
• Run pnpm --filter @tiny-design/react test — all tests pass
