* Fixed the **`ignore_models`** option in the WorldCleaner module.
* Implemented **asynchronous plugin reloading** for `/lagfixer reload` to avoid ~2-tick pauses caused by loading extensive configuration data.
* Fixed an issue where items given via `/give` appeared to “duplicate” and remained on the ground (un-pickable) when **`disable_item_despawn`** was enabled.
* Fixed the hardware menu on environments that do not support hardware detection, such as **WSL**.
* Added new **alert settings** for WorldCleaner:
  * You can now choose the alert mode (**message**, **actionbar**, or **both**).
  * Added the ability to define the **permission required** to receive alerts.
