pub async fn run_port_check() -> Result<()>Expand description
Self-check the wired port implementations. Prints a one-line summary
per port and returns Ok(()) if all are reachable.
Triggered by the OXICODE_PORT_CHECK=1 environment variable from
oxicode-cli/src/main.rs. Useful for verifying the new composition root
without disturbing the legacy App::new path.
