* chore: upgrade shadcn/ui components to v4 CLI compatibility (closes#186)
- Update 16 registry components to v4 API (function components, data-slot, radix-ui unified import)
- Migrate components.json style from new-york to radix-nova with new v4 fields (rtl, menuColor, menuAccent)
- Convert CSS variables from HSL to oklch color format with @theme inline block for Tailwind v4
- Preserve VK custom purple accent (primary/ring) in dark mode: oklch(0.389 0.15 303.5)
- Add new dependencies: radix-ui, shadcn, tw-animate-css, @fontsource-variable/geist
- Add WCAG accessibility rules, reduced-motion and focus-visible in consolidated @layer base
- Update docs/SHADCN-V4.md with v4 migration details and oklch theme reference
