Prevents selected dropped items from merging through Paper's ItemMergeEvent.
This only affects item entities in the world. It does not change stack merging inside player inventories, chests, hoppers, or other container inventories.
Materials with a maximum stack size of 1 do not produce merge events, but they may remain in the configuration for explicit policy and documentation.
