THEN Configure a fallback list of models with priority order so the agent automatically retries with the next available model on failure. Optionally support manual toggling between pre-configured models via UI without editing config files.

Define models as an ordered array with priority: [{"name": "claude-opus-4.5", "priority": 1}, {"name": "gemini-3-pro", "priority": 2}] and set strategy to "fallback".
