v0.27.2

0.27.2

• Tighten the AGP 9 Kotlin-plugin guard introduced in 0.27.1. The previous check skipped apply plugin: "kotlin-android" for any AGP 9 build, but users running AGP 9 with android.builtInKotlin=false (opting out of built-in Kotlin) still need the plugin applied. Now keyed on both the AGP major version and the android.builtInKotlin Gradle property (PR #485).
• Drop the legacy kotlinOptions { jvmTarget = "17" } block in the built-in Kotlin branch. AGP 9 defaults kotlin.compilerOptions.jvmTarget to android.compileOptions.targetCompatibility (already JVM 17), making it redundant; the legacy DSL is only available when kotlin-android is applied, so it's now gated to that branch (PR #485).
