Add Reo.dev tracking infrastructure for documentation (#8672)

* Add Reo.dev tracking infrastructure for documentation

- Add reo-tracking.js placeholder file for Reo.dev snippet
- Update docs.json to include custom JS for tracking
- Add REO_SETUP.md with detailed setup instructions
- Configure key pages for high-intent tracking

The infrastructure is ready but requires the actual Reo.dev
tracking snippet from the dashboard to be added to
docs/reo-tracking.js to enable tracking.

Fixes #8671
