Description

Enhancement Type

A completely new feature

Describe the enhancement

Add a new option that when set to true will delete the world folder on startup. Useful for minigame servers using mods such as bingo or lockout where a fresh world with a new random seed is needed for each game as a quick container restart will do all of the work.

Another option could be to allow the world option to take an empty folder and that in combination with the force copy option could be used to the same effect.

Research direction
Examine the Docker entrypoint script (e.g., start.sh) to understand how the world folder is currently handled and how environment variables are read. Look at the existing FORCE COPY mechanism mentioned in the issue to see if similar logic can be reused. Implement a new environment variable (e.g., DELETE WORLD ON STARTUP) that removes the world directory at the appropriate point in the startup sequence. Ensure it works with volume mounts and does not cause data loss unexpectedly.
