📚 Description

This registers the spa loading template as a path to restart nuxt for.

(I'll update this PR shortly to use watch hook so it doesn't need to restart, but opening it anyway to track.)

@pi0 do you think there's a way we can programmatically trigger a nitro rebuild to achieve HMR-like effect of updating spa loading template?

For future maintainability, I would create an array watchFiles and push to it (instead of directly contact edge case + filter

AFAIK rollup has no nice API for this and we really re-initialize rollup's watcher instance internally https://github.com/unjs/nitro/blob/main/src/build.ts#L528

If you're happy with us calling that nitro hook, we could instead just do that when we detect a change to the file. wdyt?

Sure you can use rollup:reload too if it works 👍🏼 (at least for Nitro 2, for Nitro 3 with other bundlers we might think of something better)
