Move to Remote Functions for Svelte

[windbyte]

The README outlines the following change:

• Fully remove tRPC and @tanstack/svelte-query when Remote Functions sveltejs/kit#13986 land

Suggestion — Do it. I'm not familiar enough with the project to figure that out.

I think I'm waiting for a few issues to be solved: sveltejs/kit#14303 sveltejs/kit#14304 sveltejs/kit#14299 sveltejs/kit#14035 sveltejs/kit#14030

or generally for the experimental flag to be lifted.
