## Summary
Emits `BreadcrumbList` JSON-LD on every `/docs/guides/*` page served by
`GuideTemplate`. Search engines and AI crawlers get an explicit
hierarchical signal for the docs site (the marketing site already
shipped JSON-LD via #45451). The chain prepends `Docs > Guides` to the
existing resolver output, so a page like `/docs/guides/auth/passwords`
produces a 5-level chain with the leaf URL set per Google's spec.
## Changes
- New `apps/docs/lib/breadcrumbs.ts`: pure pathname → chain resolver,
server-safe. Extracted from the existing client `useBreadcrumbs` hook so
the same logic runs in both contexts.
- New `apps/docs/lib/json-ld.ts`: `serializeJsonLd` +
`breadcrumbListSchema` mirroring `apps/www/lib/json-ld.ts`.
- `Breadcrumbs.tsx` (visual) now delegates to the shared resolver —
single source of truth for visual + SEO chains.
- `GuideTemplate` takes a required `pathname` prop and emits `<script
type="application/ld+json">` next to `<Breadcrumbs />`. Skipped when the
chain is empty (e.g., page not in nav menu). Middle items without URLs
(e.g., the "Auth" section root) omit `item`, matching the visual
breadcrumb.
- 8 explicit-prop callers updated; `[[...slug]]` callers already spread
`data` (which carries `pathname`).
## Scope
**Out of scope:**
- `/docs/reference/*` (SDK reference) — no breadcrumbs rendered today,
would need separate traversal over spec JSON.
- `/guides/troubleshooting/*` — uses its own template, not
`GuideTemplate`.
- `TechArticle` per-page schema — high maintenance for marginal value.
## Testing (Vercel preview)
```bash
curl -s https://<preview>/docs/guides/auth/passwords | grep -oE '<script type="application/ld\+json"[^>]*>[^<]+</script>'
```
Expect a script tag with the chain `Docs > Guides > Auth > Flows
(How-tos) > Password-based`, leaf URL
`https://supabase.com/docs/guides/auth/passwords`.
- [x] `/docs/guides/auth/passwords` — 5-item chain, leaf URL present
- [x] `/docs/guides/getting-started/features` — 4-item chain, all items
have URLs
- [x] `/docs/guides/getting-started/ai-prompts/<slug>` — special-case
chain (`Getting started > AI Tools > Prompts > <slug>`), leaf URL falls
back to pathname
- [x] `/docs/guides/database/database-advisors` (explicit-prop caller) —
chain renders
- [x] Visual breadcrumb on the same pages still renders correctly
- [ ] Validate output through [Google Rich Results
Test](https://search.google.com/test/rich-results) on a deployed preview
URL
- [x] `/docs/guides/troubleshooting/<slug>` — no JSON-LD emitted
(different template, intentional)

## Summary by CodeRabbit
* **New Features**
* Added JSON-LD breadcrumb markup to guide pages to improve
search/discovery.
* **Improvements**
* Centralized breadcrumb generation for consistent, accurate breadcrumbs
across guides.
* Multiple guide pages updated to ensure breadcrumbs and page context
display correctly.

This PR moves several components which rely on `next` out of the `ui`
package to the `ui-patterns` package.
`ui-patterns` package is intented to be imported with specific imports
so it's ok if there are components reliant on `next` in there.
The `SonnerToaster` component has removed its dependency by requiring a
prop for `theme`.
* Bump all versions of postcss to 8.5.3.
* Run next/codemod on the docs app.
* Move two experimental flags into stable. Add next-mdx-remote as a transpiled package.
* Add extra folders to the clean command in docs.
* Fix type errors in docs test.
* Run prettier on the new files.
* remove turbopack, fix fetch revalidation, fix metadata awaits
Couple of minor fixes:
- Turbopack doesn't work in dev because of known MDX loader limitations
(cannot load functions in MDX plugin config)
- Fetches not cached by default anymore in Next 15 so need to manually
cache the ones we need
- Missing a few awaits for metadata generation with page params
* Bump the graphiql version because headlessui/react is not building with Next 15.

Split guide layouts by section, so that nav data fetches can be pushed down to thesection where they're actually used. Limits blast radius of any data fetch problems, and also lets us push down client components in the future, since layouts now have context on the request path and we don't need a high-level usePathname.
