Ultimate Multiplayer EcoSystem Plugin Compatibility

All other UM Framework plugins—including Inventory (UMI), Attributes (UMAS), Skills (UMSS), Quest System, Building System, and any future UM modules—are fully compatible with this save system. Any UM plugin that uses the ISaveable pattern will automatically register, save, and load through the SaveSubsystem with no extra setup required.
