//! Embedded stdlib sources, mirrored from `harn-vm` so the module graph
//! can resolve `import "std/<module>"` without taking a hard dependency
//! on the runtime crate.
//!
//! The files are pulled in via `include_str!` from `harn-vm/src/`, which
//! makes them a single source of truth — changes to stdlib `.harn`
//! files automatically propagate to the type-checker's symbol view on
//! the next build.
