Pull request overview

This PR updates the SimulationModelsInfo JSON schema used to validate simulation model info.yml files, introducing a model_status field and adding unit tests to ensure the new constraints and backward compatibility behavior.

Changes:

• Add schema version 0.2.0 for simulation_models_info and require a new model_status field with an allowed-value enum.
• Keep schema version 0.1.0 embedded in the same schema file for backward compatibility.
• Add unit tests covering accepted/rejected model_status values and compatibility with schema_version: 0.1.0.
