/// `cargo install scsh` build reports the exact main commit it was cut from. Empty only
/// when neither source knows the commit.
///
/// Deliberately NOT a runtime `git describe`: an installed binary must report one stable
/// identity, not borrow the git state of whatever directory it happens to run in. The old
/// runtime fallback made the same binary print different hashes — and a spurious `-dirty`
/// — depending on the caller's working tree.
