devnyks/DonutSMPShop — reverse-engineered prompt

Build me a client side Minecraft mod for DonutSMP that brings back the old /shop experience as a simple vanilla looking screen. When I type /shop, I want a clean menu that makes it fast to move through categories and items, with shortcuts for Auction House search and the Shard Shop. I also want an optional Orders mode so players can quickly collect items that were already delivered.

It should only activate on DonutSMP, and it should stay fully client side. It is just a navigation helper, not a way to bypass or change how the server actually gives items. Keep the look and feel close to the original DonutSMP shop menu so it feels familiar.

Please make it for Minecraft Java Edition 1.21.11, using Fabric and Java 21, and make sure the project builds cleanly. If you need to, look up current docs online and fill in whatever is missing so it works end to end.
