Function bundle_at 

pub async fn bundle_at(
    cwd: &Path,
    folder: &Path,
    sha: Sha,
    spec: &str,
) -> Result<PathBuf, GitError>

Path-only variant of bundle for callers that cannot hold a &Repository across .await (the protocol push handler shares state across tokio tasks; gix::Repository is !Sync, so its future would not be Send).

Errors

Returns GitError::Bundle if the spec cannot be resolved, the commit graph cannot be walked, or the bundle file cannot be written. Returns GitError::Panic if the blocking task panics.
