/// Example: OhMyG0sh library usage with enhanced error handling.
///
/// This example demonstrates:
/// - Basic APK scanning
/// - Specific error type handling
/// - Performance tuning options
/// - Progress reporting
///
/// Run with:
///   dart run example/ohmyg0sh_example.dart <path_to_apk>
///
/// Exit codes:
/// - 0: Success
/// - 1: Invalid arguments
/// - 2: APK or configuration error
/// - 3: JADX error
/// - 4: Scan error
/// - 5: Unexpected error
