Airflow

This wraps the `af` CLI for hands-on Airflow operations: listing DAGs, triggering runs, reading task logs, diagnosing failures, and checking system config like connections, variables, and pools. It also covers the Astro CLI for local development and deployment. The instance management is solid, you can switch between prod, staging, and local environments with persistent config that mirrors git's system/global/local scoping. When things break, `af runs diagnose` and `af dags errors` get you straight to the problem. It routes to separate skills for writing DAGs, debugging import errors, and deployments, so this stays focused on runtime operations. Use it when you need to see what's running, fix what's broken, or just poke around Airflow state without opening the web UI.
