Example "basic-ssr-file-based": HTTP status code not set to 404 when page not found

[kcoet]

Describe the bug

Using this example: https://github.com/TanStack/router/tree/main/examples/react/basic-ssr-file-based

On a dynamic single post route, when NotFound is thrown, the http status code is not set to 404. I've scoured the documentation, it seems there is currently no way to do this.

I think this is necessary for SEO, so that non-existent pages are not indexed by search engines.

Your Example Website or App

Steps to Reproduce the Bug or Issue

Thrown NotFound on loader, see http status code.

Expected behavior

when visiting a non-existent page, the HTTP status code should be set to 404.

We're working on some new not found APIs, see #1048, that should allow for this
