Introduces configureClient({ fetch }) so apps can install a custom fetch
used by every framework-initiated client request: route-state fetches on
navigation, useRevalidate, prefetch, and <Form> submissions. Enables
forwarding an Authorization header (e.g. a bearer token held on the
client) so server-side loaders can read it from request.headers on both
the initial SSR request and every subsequent client-triggered fetch.

Summary
Add
configureClient({ fetch })API that allows apps to install a custom fetch implementation for all framework-initiated client requests. This enables forwarding auth headers (e.g.Authorization: Bearer …) to loaders on client-side navigations, revalidations, prefetches, and<Form>submissions without losing them after initial SSR.The custom fetch is routed through:
<Form>submissionsThis is particularly useful for bearer token-based auth where the token is stored on the client and must be attached to every request, unlike session cookies which flow automatically.
