compile errors when typechecking svelte.config.js with moduleResolution set to nodenext

[DetachHead]

Describe the bug

when typechecking svelte.config.js with moduleResolution set to nodenext, the following compile errors occur:

❯ tsc svelte.config.js --allowjs --noemit --moduleresolution nodenext
node_modules/@sveltejs/kit/types/index.d.ts:6:32 - error TS2307: Cannot find module 'svelte/types/compiler/interfaces' or its corresponding type declarations.

In Svelte 4 this will be exported from svelte/compiler, so once we bump the minimum required Svelte version we can fix this

I sent #11188 for SvelteKit

@sveltejs/enhanced-img uses a bunch of types that don't appear to be available in svelte/compiler, so maybe we need to export some more stuff for it?

[dummdidumm]

Which ones are these?

[benmccann]

import('svelte/types/compiler/interfaces').TemplateNode
import('svelte/types/compiler/interfaces').BaseDirective | import('svelte/types/compiler/interfaces').Attribute | import('svelte/types/compiler/interfaces').SpreadAttribute

[dummdidumm]

Mhm I feel like those are somewhat private, we haven't made the AST public API until now, so I'd prefer if for now @sveltejs/static-image maintains their own versions of these.

[benmccann]

Ok. I will close this as completed then
