How to use with react router clientLoader?

If you want ssr only on first render for seo and then go spa mode, using `loader` and `clientLoader` at the same time (after first render `loader` will be skipped on navigation and `clientLoader` used instead), how can we do this?

Start by reviewing the React Router loader and clientLoader behavior described in the issue, then inspect the Apollo Client Next.js App Router integration for SSR and navigation handling. Confirm whether first-render SSR for SEO followed by SPA navigation is supported, and document the required configuration or limitation.
