zPeanut/hydrogen ? reverse-engineered prompt

Build me a Minecraft 1.8.9 Forge mod that works like a ghost client and feels polished for everyday use.

I want it to have a big set of modules, around 50 or more, focused on combat, rendering, and useful quality of life features. It should include a clean in game click GUI that is easy to customize, plus a simple settings system so users can turn things on and off without editing files. Please make it run through Forge and use mixins where that makes sense, since the project is built that way.

Also add a version check so the client can tell when it is out of date, and make sure the code is easy to build with Gradle and export as a jar people can drop into their mods folder. If anything is unclear, look up the current Forge and mixin docs online before implementing it.
