Commands

The `validate` command ensures that committed files match the expected output. It processes all `page.mdx` files to verify parent indexes are up-to-date, all `types.ts` files to ensure generated `types.md` documentation is current, and — when `withFairGardenDocs` is configured with `requireDemoClient` or `requireDemoPage` — ensures every demo `index.ts` has a sibling `client.ts` wired through `ClientProvider` and/or a sibling `page.tsx` that renders the demo as its own route.
