Migrate the project from Gradle Kotlin DSL to Groovy DSL: update README to reference build.gradle/settings.gradle and change code blocks to Groovy. Remove build.gradle.kts. Add runServerJar and runServer tasks in build.gradle that depend on shadowJar and launch the Hytale server (uses hytaleHome paths, assets, and optional user mods). Bump plugin manifest version to 0.0.3 and set a concrete ServerVersion string. Fixed some issues.
Adjusted the paths in build.gradle.kts to reference the correct locations for HytaleServer.jar and Assets.zip. Updated README to reflect changes in the server's mods folder instead of plugins folder for clarity.
Expanded README with detailed usage instructions and features for the Run Hytale Server Gradle plugin. Updated build.gradle.kts to use a Paper server JAR as a placeholder for testing the runServer functionality.
Add a minimal, ready-to-use Hytale plugin template including Gradle build scripts, GitHub Actions CI workflow, example plugin class, configuration and manifest files, and supporting documentation. This setup provides modern build tooling, automated server testing, and best practices for plugin development.
