Decocraft

Refactored recipe registration to correctly initialize the Decobench, Decomposer, and Decobrush.

Added Coal as a valid input for the Decomposer.

Implemented sitting node support for the Gym Bench.

Corrected texture reference for Monkeybars and standardized several flag texture names.

Improved GUI safety — items clicked in deadspace are now automatically returned to the player's inventory instead of being dropped.
