// Finds the workspace / project and scheme (native, Capacitor ios/App, React Native ios/<Name>, Flutter ios/Runner,
// Unity Unity-iPhone), takes the next safe build number from App Store Connect (apple next-build) unless
// --build-number is given, writes <out>/ExportOptions.plist (method app-store-connect, team, signing style and the
// profiles from apple.signing), runs xcodebuild archive and -exportArchive with the API key
// (-allowProvisioningUpdates -authenticationKey*), and leaves <out>/export/<version>-<build>/<App>.ipa for `storebound apple upload`. Each build exports into its own
// folder, cleaned first: xcodebuild refuses to overwrite an earlier App.ipa ("exportArchive Copy failed", pitfall 53).
// Full xcodebuild output goes to <out>/xcodebuild-*.log; the terminal gets the result lines.
// Local only: nothing is sent to App Store Connect except reads (build numbers, team id, profiles).
