kmp-migration-skill

Use this skill whenever a user wants to migrate a Kotlin Multiplatform (KMP) or Compose Multiplatform project from the old single-module structure (with a `composeApp` module) to the new default structure (with a `shared` library module and separate `androidApp`, `desktopApp`, `webApp` application modules). Also trigger for questions about the new KMP project structure, what changed in the KMP wizard, how to split `composeApp` into separate modules, stale Android Studio or IntelliJ run configurations that still show `composeApp`, or how to comply with Android Gradle Plugin (AGP) 9.0's requirement to separate app and library code. Use this even if the user phrases it casually, e.g. "how do I update my KMP project structure", "split my composeApp module", "composeApp still appears in Edit Configurations", or "AGP 9.0 breaking my KMP build".
