@siemens/ix-vue: Incorrect type declaration path breaks TypeScript builds

What happened?

Description
When importing components from @siemens/ix-vue in TypeScript project, the TS compiler fails with the following error:

Could not find a declaration file for module '@siemens/ix-vue'. 'node_modules/@siemens/ix-vue/dist/index.js' implicitly has an 'any' type.
  Try `npm i --save-dev @types/siemens__ix-vue` if it exists or add a new declaration (.d.ts) file containing `declare module '@siemens/ix-vue';`

---

Cause of the Bug
The root cause seems to be that the @siemens/ix-vue package contains a mismatch between the declared types entry in its`package.json package layout and the actual file structure:

In the package.json of @siemens/ix-vue, the types key points to:

"types": "dist/index.d.ts"

The build process seems to output the declaration files nested inside src within the dist directory. The actual types file is located at:

node_modules/@siemens/ix-vue/dist/src/index.d.ts

Because TypeScript expects type definitions to be located in dist/index.d.ts, it fails to resolve types for this package, thus resulting into the TS compiler error.

---

Steps to reproduce

1. Create a Vue 3 project with TypeScript.
2. Install @siemens/ix-vue (v5.1.1).
3. Import any component in a .vue or .ts file:

import { IxApplication } from "@siemens/ix-vue";

4. Run standard TypeScript checks (e.g., vue-tsc --noEmit).

---

Temporary Workaround
Add the following workaround to your project's tsconfig.json paths mapping to pinpoint the current location of the type declaration file:

{
  "compilerOptions": {
    "paths": {
      "@siemens/ix-vue": ["./node_modules/@siemens/ix-vue/dist/src/index.d.ts"]
    }
  }
}
