Svelte 5: +layout.svelte children not included in zero-effort type safety

[eddiemcconkie]

Describe the bug

The $props for +layout.svelte files should include children, alongside data and form for zero-effort types. You can manually type children as Snippet, but then you have to manually type data and form as well.

Reproduction

<!-- /routes/+layout.svelte -->
<script lang="ts">
  const { children } = $props();
</script>

{@render children()}

<!-- /routes/+page.svelte -->
<h1>Page content</h1>

Expected behaviour

children is included in $props for +layout.svelte files
