// Embeds a best-effort short git SHA into the build for provenance
// (`cera::build_info()` / `cera::GIT_SHA`). Consumers such as the Pipette
// benchmark app report it alongside results, the way llama.cpp surfaces its
// build commit. Falls back to "unknown" when git is unavailable (e.g. a
// packaged source build with no repository), and can be overridden explicitly
// by setting `CERA_GIT_SHA` in the build environment (used by release CI for a
// deterministic value).
