The GNU tar CI job depends on git.savannah.gnu.org, which can fail transiently during clone or submodule setup. Retry those network-dependent setup steps with exponential backoff before failing the job. Keep cleanup scoped to failed clone attempts, fail early if path_GNU already points at a non-git directory, and tighten the helper script with pipefail and shellcheck-clean quoting.
