I noticed during testing that I'm not sure we ever handled meta types for clientLoader. I think as long as we always union with undefined this should be valid since meta would have no data on initial render for clientLoader-only routes.

Hybrid routes are trickier because meta would have data for the server loader on SSR, and on initial hydration and then would have clientLoader data subsequently - but I think that's just a userland solution via MetaFunction<typeof loader | typeof clientLoader>
