+/// Push a specific ref to a relay.
+///
+/// This is used for pushing to refs/nostr/<event-id> for PR events.
+/// Unlike `push_to_relay` which pushes all refs, this pushes a specific
+/// commit to a specific ref name.
+///
+/// # Arguments
+/// * `local_path` - Path to local git repository
+/// * `relay_domain` - The relay domain (e.g., "127.0.0.1:8080")
+/// * `npub` - Owner's npub
+/// * `repo_id` - Repository identifier
+/// * `commit_hash` - The commit to push
+/// * `ref_name` - The ref name to push to (e.g., "refs/nostr/<event-id>")
+///
+/// # Returns
+/// * `Ok(())` - Push successful
+/// * `Err(String)` - Push failed
