Stand up build.sx (macos + ios/ios-sim targets, bundle id co.swipelab.m3te, output sx-out/ios/M3te.app, assets dir) and a minimal main.sx that brings up the platform (UIKit+Metal on iOS, SDL3+GL on macOS) and renders a solid-clear frame. Add assets/ and goldens/ directories and a .gitignore for build artifacts. Modeled on game/build.sx and game/main.sx; modules resolve from the compiler binary with no -L flag.
