## Title

    Proposed fix: [SWE-agent] Local/unknown model: ModelConfigurationError 'Error calculating cost: ... If this is ok (local models, etc.), please make sure you set `per_instance_cost_limit` and `total_co

## Body

    Recommended action: Set per_instance_cost_limit and total_cost_limit to 0 and bound runs with per_instance_call_limit, or register prices via litellm_model_registry.
    
    Option: Set per_instance_cost_limit and total_cost_limit to 0 and bound runs with per_instance_call_limit, or register prices via litellm_model_registry. [evidence: official_recommended_action]
    Applies when: Running SWE-agent with a local, proxied or new model not in litellm's cost map
    Steps:
    1. agent.model.per_instance_cost_limit: 0
    2. agent.model.total_cost_limit: 0
    3. agent.model.per_instance_call_limit: <N>
    4. Or provide litellm_model_registry JSON with cost info
    Expected: The error no longer appears.
