ItemCleaner

• ✅New Multiple Cleanup List Management System：Supports creating multiple independent cleanup lists (e.g., default list, dedicated cleanup lists, etc.) for flexible switching between scenarios; provides a complete set of management commands:

/cleandrops listmanager create <name>：Create a new list
/cleandrops listmanager switch <name>：Switch current list
/cleandrops listmanager delete <name>：Delete specified list (at least one list remains)
/cleandrops listmanager current：Check currently active list
/cleandrops listmanager all：Display all available lists
/cleandrops listmanager list：View all lists and their included items

• ✅ Admin Item: Admins can obtain the Cleanup Hoe from the creative inventory or by using the command /give @s itemcleaner:cleanup_hoe. Hold it in hand and right-click to instantly remove all item drops listed in the cleanup configuration.
• ✅Enhanced List Management Features：Each list can be independently configured with cleanup items, supporting cross-list rule isolation; new rules are automatically applied when switching lists without restarting the game; currently active list is marked with * when displaying lists for intuitive status distinction
• ✅Optimized Configuration File Structure：Added currentCleanupList field to record the name of the current list; added cleanupLists object to store multiple lists as key-value pairs (keys are list names, values are item ID lists); retained default list (default) and added example list (NowClean) for quick start
