Does a number of things to check the version more often:

Adds a header to responses with the version, so that any request SvelteKit initiates is an opportunity to discover the client needs an update
Checks the version on visibilitychange and window.focus events
Polls once an hour

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`. ⚠️
