Replaces the previous Kotlin-based Gradle build and template files with a new Java-based Gradle build system and updated example plugin code. Removes old build scripts, plugin template, and configuration, and introduces a new ExamplePlugin with updated manifest, command, and recipe example. Updates documentation and project configuration to match the new structure and usage.
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.
