svelte@5.0.0-next.157 breaks `svelte-check`

[lts20050703]

Describe the bug

svelte@5.0.0-next.157 breaks svelte-check (and intellisense)

When trying to run svelte-check errors such as the following will appear (as well as VSCodium will scream at me)

• Error: Cannot find name '$state'.ts(2304)
• Error: Cannot find name '$derived'.ts(2304)
• Error: Cannot find name '$effect'.ts(2304)
• ...

I'm not sure if this is a bug in svelte or the svelte-check tool needs to be updated, so feel free to close this one if it's svelte-check tool needs to be updated. (The other bug report: sveltejs/language-tools#2405)

Reproduction

1. npm install svelte@5.0.0-next.157

<script>
let x = $state()
let y = $derived(x * 2)
$effect(() => {
  console.log("Mounted")
})
</script>

Downgrading to svelte@5.0.0-next.155 fixes this issue for me -- seems likely this is an issue in 157.
