//! el-build — Build orchestrator for the Engram language toolchain.
//!
//! Reads `el.toml`, resolves dependencies, compiles source files, and produces
//! artifacts. Supports incremental builds via BLAKE3 file hashes stored in
//! `.el/build-cache.json`.
//!
//! # Usage
//! ```rust,no_run
//! use el_build::BuildSystem;
//! use el_manifest::Manifest;
//!
//! # async fn example() -> Result<(), Box<dyn std::error::Error>> {
//! let manifest = Manifest::from_file(std::path::Path::new("el.toml"))?;
//! let bs = BuildSystem::new(manifest, std::env::current_dir()?);
//! let output = bs.build(None).await?;
//! println!("artifact: {}", output.artifact_path.display());
//! # Ok(())
//! # }
//! ```
