arxdeus/xcross ? reverse-engineered prompt

Build me a tool called xcross that lets me run and hot reload Flutter iPhone apps directly from Windows or Linux, without needing a Mac, Xcode, or WSL.

I want it to take a Flutter project, build the iOS debug app with the available Swift and LLVM toolchains, sign it with either an Apple ID or an App Store Connect API key, install it on a real iPhone, and launch it with full hot reload and hot restart support. It should also handle the setup work for me, like checking for missing dependencies, helping install them, and setting up the iOS SDK from an Xcode archive without actually requiring Xcode to run.

Make it feel like a normal command line tool with clear commands for setup, signing in, installing the SDK, running the app, checking for updates, and connecting IDE debugging if possible. If you need to look up current docs or APIs, do that.
