baier233/nobody-client ? reverse-engineered prompt

Build me a Minecraft JNI client that injects into the game and works as a base for a lightweight mod menu. I want it to support Lunar Client, Forge, and vanilla or Badlion on the versions listed in the README, with the strongest support for 1.8.9 and 1.12.2, and only limited support where that project says it is limited.

Please set up the core client structure, injection flow, and whatever is needed to hook into the game cleanly. If there are missing pieces or old code patterns, modernize them and make the project easier to extend. Keep it practical, make it compile, and organize it so new modules can be added without everything turning into a mess.

If you need current JNI or Minecraft related docs to avoid getting stuck, look them up online and then implement the best version you can.
