linter ignores jvmtarget gradle config


That's in my build.gradle file:
```build.gradle
tasks.withType(JavaCompile).configureEach {
it.options.release = 21
}

tasks.withType(org.jetbrains.kotlin.gradle.tasks.KotlinCompile).all {
kotlinOptions {
jvmTarget = 21
}
}
```

IntelliJ seems to be okay with it. And it compiles.

Start with the build.gradle snippet and reproduce the linter behavior using the JavaCompile release and KotlinCompile jvmTarget settings shown there. Trace how the language server reads these Gradle configurations and verify that the linter recognizes the configured JVM target while preserving the existing IntelliJ-compatible compilation behavior.
