buddymeteor/Meteor-autosell ? reverse-engineered prompt

Build me a Fabric Minecraft mod for 1.21.1 that helps with auto selling items on a server like DonutSMP.

I want it to open the sell menu with a chat command, move items into the sell GUI automatically, click the confirm button, and keep repeating the process. Please add a small in game HUD that shows things like current money, total sold, money per hour, uptime, and whether it is running. I also want a simple config screen and saved settings so I can turn features on and off easily.

Please include safety features too, like pausing if I move too far from the sell spot, returning me back if I get pushed away, and detecting admins or nearby players so it can stop or disconnect if someone suspicious is close. Add a whitelist so trusted players do not trigger alerts. If possible, send Discord webhook alerts when sales happen or when a player or admin is detected.

Make it clean, open source, and easy to build and install.
