Fallback to the default, Java 17. Seems no need to require it running on Java 21.

Let's check after the merge; I remember it was needed

80-85: Approve centralized Kotlin compiler configuration.

The KotlinCompile task configuration cleanly centralizes language and release targets across all projects. The combination of jvmTarget and -Xjdk-release ensures consistent bytecode generation and cross-compilation compatibility.

---

76-85: API contract verified—no issues found.

The centralized configuration is correct. JvmTarget.fromTarget() is a public Kotlin API that accepts string parameters, and libs.versions.jdkRelease.get() returns "17", which is a fully supported target version. The call at line 82 follows the documented API usage pattern and will produce the expected enum value JvmTarget.JVM_17.

The subproject override in tools/idea-plugin/build.gradle.kts (hardcoded to JvmTarget.JVM_21) is intentional and documented with a comment explaining the IDEA 2024.2+ requirement.
