Pull Request Overview

This PR refactors the zone configuration system to adapt for the autonomy command by updating domain references and default configuration file names. The changes migrate from "ockam" branding to "autonomy" branding while maintaining backward compatibility.

• Updates the HTTP URL domain from ai.ockam.network to cluster.autonomy.computer
• Changes default configuration file search order to prioritize autonomy.yaml and autonomy.yml over ockam.yaml and ockam.yml
• Updates documentation to reflect the new configuration file search behavior
