Ender Excavator's Harness

create a minecraft item that has the following description: 'Crafting: 1 Netherite Block, 1 Heart of the Sea, 4 Shulker Shells, 2 Ender Chests. Effect: A wearable item (chest slot). When worn, any block that you mine (that drops itself, e.g., stone, dirt, wood) has a 50% chance to be directly placed into an empty Shulker Box in your inventory (prioritizing one with space for that block type). If no space, it drops normally. Does not work on ores or special drops. Purpose: Drastically reduces inventory management during large-scale excavation, allowing continuous mining without stopping to empty inventory. Balancing: Only works on specific blocks, 50% chance, requires empty Shulker Boxes, takes an equipment slot, incredibly expensive.'
