test(fixtures): add vite-kitchen fixture repo

Minimal Vite + React + TS + Tailwind app with a typed-props Button
component (the future react-docgen-typescript scan target), landed at
fixtures/ outside the pnpm workspace and turbo graph. Its dependencies
exist on paper only — the runner installs them after cloning (story 04);
no lockfile, never pnpm-installed here.

Ignore surfaces follow the docs/product/reference precedent: fallow,
root ESLint, prettier, and the coverage:diff ALLOWED_GLOBS all skip
fixtures/**.
