✨ New "Worker" Animation & Customization

Lifelike Animation:
Now, when you use commands like /set or /wall, a personal worker NPC appears beside you. This worker teleports to each placement location, focuses on the task with head movement, and swings their arm to simulate actually placing the block!

Fully Customizable:

• Head: The worker’s head uses the skin of the player who issued the command.
• Equipment: They hold the block currently being placed.
• Armor: You can customize the color of their leather armor using any RGB value in the config.yml.
• Size & Positioning: You can now control the worker's size (small/big) and vertical offset (y-offset) from the config.yml.
  

Improvements & Enhancements

Single Worker Rule:
While a player has an active construction task, they cannot run another build command. This prevents bugs and reduces unnecessary load on the server, ensuring a more stable experience. A new warning message (task-already-running) has been added to the config.yml for this situation.
