//! Capture the git short SHA (and a dirty flag) at build time so the
//! `analyzer` version banner can report the exact commit the binary was
//! built from. Non-fatal: outside a git worktree (a crates.io or source
//! tarball, `cargo package`'s verification build) vergen emits nothing
//! and `build_info.rs` reads the variables with `option_env!`, so the
//! banner reports `unknown`. Note that vergen does not return an error
//! in that case — it only warns — which is why the fallback lives on
//! the reading side rather than here.
