///
/// # Features
///
/// - Multi-platform compatibility analysis
/// - Architecture-specific optimization detection
/// - Container and cloud platform support
/// - GPU and accelerator compatibility
/// - Performance benchmarking and profiling
/// - Regulatory compliance assessment
/// - CI/CD pipeline integration analysis
