Reproduction

Describe the bug

1. addTypeTemplate adds the file to vue.script.globalTypeFiles.
   

   nuxt/packages/kit/src/template.ts

   Lines 101 to 108 in ce14d05

   	if (!context || context.nuxt || context.shared) {
   	// expose global types to vue compiler
   	nuxt.options.vite.vue = defu(nuxt.options.vite.vue, {
   	script: {
   	globalTypeFiles: [template.dst],
   	},
   	})
   	}

2. compiler-sfc registers the file scope as global.
   https://github.com/vuejs/core/blob/e9c676f/packages/compiler-sfc/src/script/resolveType.ts#L824-L834

3. compiler-sfc only resolves exported types that are not in the global file scope.
   https://github.com/vuejs/core/blob/e9c676f/packages/compiler-sfc/src/script/resolveType.ts#L1316-L1370

4. Types imported from added files cannot be used as input for defineProps.

   import type { Foo } from "#build/foo";
   
   defineProps<Foo>(); /* [@vue/compiler-sfc] Unresolvable type reference or unsupported built-in utility type */

Additional context

This issue requires compiler-sfc to run resolveGlobalScope before resolving the props of components that import added files. If you remove the script block in app.vue, you will find the error disappears.

Workaround: use addTemplate with write: true.
