Usage: $(basename "$0") [command] [options]

Commands:
  build            Build ${APP_NAME}.app for the current architecture (default)
  build-universal  Build a universal (arm64+x86_64) ${APP_NAME}.app
  clean            Remove build artifacts
  run              Build (if needed) and run the app
  debug            Build (if needed) and run in foreground with verbose logs
  package          Zip the built app into dist/${APP_NAME}.zip

Options (for build):
  --arch <arch>    Build for a specific arch (arm64 or x86_64). Defaults to host arch.
  --verbose        Print verbose build commands (same as PROLE_VERBOSE=1)

Examples:
  ./build.sh build
  ./build.sh build --arch arm64
  ./build.sh build-universal
  ./build.sh run
  ./build.sh package

Dependencies:
  IRC and RoyalVNC are built via Swift Package Manager.

Environment overrides (optional):
  ROYALVNCKIT_XCFRAMEWORK   If set, use this RoyalVNCKit.xcframework instead of building
  KEEP_DEPS=1               Keep the deps staging directory after the build (for debugging)
  PROLE_VERBOSE=1           Stream verbose output from SwiftPM/xcodebuild and echo commands
