Svelte 5: Setting `compilerOptions.runes` to `false` doesn't respect `$$props`

[AdrianGonz97]

Describe the bug

When setting compilerOptions.runes to false, the compiler thinks I'm attempting to use $props when I'm really trying to use $$props.someProp.

Current workaround is to remove the compiler option from svelte.config.js and just disable runes locally with <svelte:options runes={false} />.
