- Removed explicit Kotlin Gradle Plugin (KGP) application to comply with Flutter 3.24+ Built-in Kotlin standards and suppress KGP warnings.
- Wrapped `kotlinOptions` in `project.pluginManager.withPlugin("org.jetbrains.kotlin.android")` to prevent `Could not find method kotlinOptions()` crashes on older Flutter SDKs.
- Ensured Java and Kotlin JVM targets are uniformly configured to JavaVersion.VERSION_17 to prevent compilation mismatch errors.
- Bumped package version to 0.3.1.
