## I have read the CONTRIBUTING.md file.
YES
## What kind of change does this PR introduce?
Dependency upgrade (next-mdx-remote v4 → v6)
## What is the current behavior?
The docs app uses next-mdx-remote v4.4.1 with MDX v2.
## What is the new behavior?
- Upgraded to next-mdx-remote v6.0.0 (uses MDX v3)
- Updated @mdx-js/loader and @mdx-js/react to v3
- Upgraded remark-gfm to v4 for MDX v3 compatibility
- Removed deprecated `useDynamicImport` option (now default)
- Added `blockJS: false` to preserve JS expressions in MDX content
Build compiles successfully. Testing shows the same pre-existing
prerender error on /guides/troubleshooting as on master (supabaseUrl is
required).

## Summary by CodeRabbit
* **Chores**
* Upgraded MDX and markdown tooling to major releases (MDX v3,
next-mdx-remote v6, remark-gfm v4).
* Adjusted MDX serialization to disable embedded JS handling and remove
legacy dynamic-import behavior for more consistent rendering of docs,
guides, and code examples.
