ManaZZZ/Villager-Trading-Predictor — reverse-engineered prompt

Build me a Minecraft Java mod called Villager Trading Predictor. I want it to help me decide if a villager is worth keeping by predicting what enchantment trades it will offer as it levels up, so I do not waste time rerolling bad villagers.

Add a simple in game GUI that opens with /vtp, plus a small HUD that can be turned on and off. I should be able to set the target enchantment and level I am looking for, set the world or server seed for multiplayer, choose the maximum number of rerolls to search, and calibrate the prediction if the trade list is offset. The calibration should let me enter one or more known enchantments and levels, then confirm which reroll round I am on.

Please make the commands clear and forgiving, and make the display easy to understand at a glance. Use the existing project setup, and look up current Minecraft modding docs online if needed.
