Closes #11190

modulepreload is now baseline 2023: https://caniuse.com/?search=modulepreload

I left the type so that it will show up in the docs still for users on older versions of Kit

Removed the test from the options app because modulepreload only gets written when not prerendering

@benmccann benmccann added this to the 3.0 milestone Feb 5, 2026

This PR was opened by the [Changesets
release](https://github.com/changesets/action) GitHub action. When
you're ready to do a release, you can merge this and the packages will
be published to npm automatically. If you're not ready to do a release
yet, that's fine, whenever you add more changesets to version-3, this PR
will be updated.

⚠️⚠️⚠️⚠️⚠️⚠️

`version-3` is currently in **pre mode** so this branch has prereleases
rather than normal releases. If you want to exit prereleases, run
`changeset pre exit` on `version-3`.
