dscalzi/HeliosLauncher ? reverse-engineered prompt

Build me a polished desktop launcher for a modded Minecraft server, basically like Helios Launcher. I want it to be easy for normal players to use, so they can sign in, manage multiple accounts, pick a server, see player counts, read launcher news, check Mojang service status, and launch the game without having to manually install Java, Forge, Fabric, or mods. The launcher should validate files before launch, redownload anything missing or broken, and update both the game files and the launcher itself automatically.

Make it feel clean and modern, with a proper settings area including Java controls, and support Windows, macOS, and Linux builds. Microsoft login should work, and Mojang account support too if it still makes sense. Please wire it up as an Electron and Node desktop app like this project, keep it runnable locally with npm start, and make sure production installers can be built. If anything about auth or current platform requirements has changed, look up the latest docs and update the implementation accordingly.
