Add WorldManager and map-system support

Introduce WorldManager to select and unpack a random map ZIP into the server root before startup. The plugin now calls WorldManager.prepareRandomWorld() in onLoad (before onEnable) and reloads config there. Added map-system config options (enabled, zip-folder, target-world-name, maps) with example entries. WorldManager deletes existing world folders, extracts the chosen ZIP (with zip-slip protection) and logs progress.
