First-class SvelteKit integration (load, form actions, streaming SSR)

[bmarkov]

There's a create-svgrid scaffold and an admin-dashboard template already, but I want SvGrid to feel genuinely native to SvelteKit - not just a component you drop in.

What I'm picturing is a small first-party integration: helpers for load (server sort/filter/paging that line up with the grid's models), form-action wiring for edits, and streamed SSR so the first rows paint before the rest arrives.

It's on the roadmap here: https://svgrid.com/roadmap

If you build on SvelteKit, what would make this a no-brainer - the load helpers, the form actions, something else?
