3//! Release command - builds production-optimized binaries with codegen mode
4//!
5//! This command wraps `cargo build --release` with the `codegen` feature flag,
6//! providing optimized production builds with zero runtime overhead.

36///
37/// - **Release Mode**: Compile-time code generation with full optimizations
38/// - Zero runtime overhead for maximum performance
39/// - Ideal for production deployments
40/// - Requires build.rs for code generation
