Crafter Recipe Lock

Adds a lock button to the Crafter interface, letting you lock and unlock its nine-slot pattern. Locking preserves the selected ingredients, empty positions, and disabled slots.

Prevents accidental manual changes and incompatible hopper insertions while allowing normal crafting and restocking with identical ingredients. The pattern stays saved even when materials run out and persists across world saves and reloads.

Compatible with Minecraft Java 26.2 and Fabric.
