Types from `@ember/helper` do not include working types for `uniqueId`

[NullVoxPopuli]

🐞 Describe the Bug

missing types

🔬 Minimal Reproduction

just import it in a ts/gts file

😕 Actual Behavior

no types

🤔 Expected Behavior

types

🌍 Environment

• Ember: - 6.7.0-alpha.1
• TS - 5.8.3
• @glint/core - 2.0.0-alpha.2

➕ Additional Context

This happens because uniqueId is a re-export from @ember/-internals/glimmer

@ember/-internals/glimmer is in the published types/ directory, but this index.d.ts in that folder is missing all the sub-modules

In particular:

// in: ember-source/types/stable/@ember/-internals/glimmer/index.d.ts
export { uniqueId } from "@ember/-internals/glimmer/lib/helpers/unique-id";

so this file is defined:

declare module '@ember/-internals/glimmer/lib/helpers/unique-id' {
    /**
    @module ember
    */
    const _default: object;
    export default _default;
    export function uniqueId(): string;
}

the @module is wrong.. idk what's going on with that.

but anyway,
referencing a declare module is one thing -- but it first has to be loaded in to the TS program in order to be correctly referenced in the first place.

That referencing happens in ember-source/types/stable/index.d.ts

And does include 'unique-id':
