Ivan Vasilov c6cdf4bd53 Migrate off contentlayer2 to Velite (design-system, ui-library, learn) (#48546)
## Summary
- `contentlayer2@0.4.6` is unmaintained and drags in a heavy, stale
dependency graph (esbuild pinned to 0.17–0.20, mdx-bundler, old
`@opentelemetry/core`) that was the recurring source of vuln bumps.
- Migrates all three apps that used it — `design-system`, `ui-library`,
`learn` — to [Velite](https://velite.js.org), preserving the generated
typed `allDocs`/`Doc` collection and the `body.code` + `useMDXComponent`
runtime via a small shared local hook.
- Same MDX pipeline (remark-gfm, remark-code-import, rehype-slug,
rehype-pretty-code w/ Shiki compat + local theme,
rehype-autolink-headings, custom
`__rawString__`/`__src__`/`__event__`/`__style__` visitors) ported 1:1
into each app's `velite.config.js`.
- `learn`'s extra frontmatter fields (`chapterNumber`, `explore`,
`courseHero`) are now backed by real Velite/Zod schema types, so the
`(doc as any)` casts in `get-next-page.ts` / `get-current-chapter.ts` /
the doc page could be dropped.
- `next.config.mjs` no longer wraps with `withContentlayer`; since
Velite has no Next.js webpack-plugin equivalent, each app's `dev` script
now runs `velite dev` and `next dev` in parallel via `npm-run-all`.

## Test plan
- [x] `pnpm build:content` (Velite build) succeeds for all three apps
- [x] `pnpm typecheck` passes for all three apps
- [ ] Manual smoke test of `pnpm dev` for each app in a browser (docs
pages render, TOC, copy-button, code highlighting)

This is a Next.js project bootstrapped with create-next-app.

Getting Started

First, run the development server:

npm run dev
# or
yarn dev
# or
pnpm dev
# or
bun dev

Open http://localhost:3000 with your browser to see the result.

You can start editing the page by modifying app/page.tsx. The page auto-updates as you edit the file.

This project uses next/font to automatically optimize and load Inter, a custom Google Font.
