Kotlin development

1. Scope+inspect

1. DEFINE change: source | build | test | Java interop | coroutine | KMP source set.
2. RECORD affected modules, targets, public API, runtime, minimum Kotlin/Java/Gradle/Maven/AGP/native toolchain.
3. PRESERVE current build/Kotlin/language/API/plugin/style/test versions unless migration requested.
4. Version/new API => READ current docs+releases.
5. RUN from target root:

   python3 scripts/inspect-project.py --root . --json
   

6. VERIFY detected build, wrapper, files, plugins, source sets, targets, Kotlin count.
7. JIT READ:
   • build/deps/toolchain/version -> references/build-tools.md
   • KMP plugin/source sets/multi-target -> references/multiplatform.md
   • null/Java/coroutine/public API/style -> references/language-safety.md
   • test framework/layer -> references/testing.md; example-based test structure/refactoring -> arrange-act-assert
