Add md-react-preview for doc preview

[IzumiSy]

Summary

Integrate md-react-preview (@izumisy/md-react-preview@^0.2.0) to provide live interactive previews for component documentation pages.

Background

AppShell's component catalog is managed and published as unified documentation on docs.tailor.tech. The data source for docs.tailor.tech is the Markdown files under the docs/ directory in this repository, which are synced to VitePress for rendering.

We also want to provide Storybook-like live component previews on docs.tailor.tech. However, since the documentation is authored in the AppShell repository but served from a separate site (docs.tailor.tech), we needed a streamlined process to deliver a consistent preview experience across both environments.

To solve this, we built md-react-preview (mrp). mrp provides both a Vite plugin and a VitePress plugin that share the same preview rendering core, enabling:

• AppShell repository: Run pnpm docs:preview to preview documentation locally
• docs.tailor.tech: The same previews are rendered in production via the VitePress plugin

This allows documentation authors to simply write preview code in Markdown and get identical results both locally and in production.

Changes

• Added @izumisy/md-react-preview (^0.2.0) and @tailwindcss/vite as dev dependencies
• Added mrp.config.ts — configures md-react-preview to scan docs/components/**/*.md with AppShell's CSS
• Added docs:preview script — runs mrp dev to start the documentation preview server
• Updated all component docs (docs/components/*.md) to use the new preview block syntax:
  • Preview code blocks now use export default (...) instead of bare JSX / ;-prefixed expressions
  • Multi-element previews are wrapped in <>...</> fragments
  • Removed semicolons from import statements inside preview blocks
• Minor doc cleanups — removed redundant import sections and trimmed unnecessary content from some component pages

How to test

pnpm install
pnpm docs:preview
