Update to latest

Rather than updating official documentation with [manual steps](https://kotlinlang.org/docs/native-get-started.html#before-you-start) how to fix this project how about updating this repo to have up-to-date code instead?

Start by reviewing the repository contents and comparing the current project setup with the linked Kotlin/Native documentation, especially its “Before you start” guidance. The issue is complete when this starter project reflects the current setup without requiring the documented manual fixes, but the exact files and validation steps are not specified.
