//! Captures compile-time git metadata exposed via `aleph --version`:
//! - `ALEPH_GIT_COMMIT`: short SHA of HEAD, with `-dirty` suffix if the working
//!   tree has uncommitted changes.
//! - `ALEPH_COMMIT_DATE`: ISO date of the HEAD commit.
//!
//! Falls back to "unknown" when git is unavailable (e.g. building from a release
//! tarball without `.git`).
