sakuracheatservices/phantomclient-source-code — reverse-engineered prompt

I have this Phantom Java source folder and I want you to turn it into a clean working project I can open, build, and run without fighting Gradle errors.

Please inspect the code, fix whatever is broken, update the Gradle setup only as much as needed, and make sure the GUI opens with the P key like the README says. Since this source mentions a removed RAT, please carefully check for anything sketchy like remote access code, token grabbing, hidden downloads, weird webhooks, or background persistence, and remove or disable it. I only want a safe local client build.

Keep the original behavior as much as possible, but make the project easier to use. Add simple run instructions in the README, explain what Java version is needed, and make sure the build works from a fresh clone. Look up current docs online if you need to.
