Apply Figma design tokens: palette, typography, semantic aliases ...

- Replace placeholder colors with extracted Figma primitives:
  neutral, lavender, mint, yellow scales and danger/info/success/warning
  semantic primitives.
- Add semantic aliases for surfaces, borders, and UI states.
- Replace IBM Plex Mono with Plus Jakarta Sans as primary font.
- Add full typography scale (headings, body, button, caption)
  for mobile and desktop from Figma Style Guide.
- Update docs/style-guide.md with extracted tokens.
- Update .gitignore to exclude .figma-token.
- Update vmk-ui-kit-figma.url to point to the shared copy.

Build, Vue example build, and Playwright smoke test still pass.

Build, Vue example build, and Playwright smoke test all pass.
