Pull request overview

This PR extends the Python SDK’s model metadata surface area to include additional “capability” fields (context length, modalities, capabilities, tool-calling support) and adds tests to ensure these new properties are exposed consistently on both Model and ModelVariant.

Changes:

• Add context_length, input_modalities, output_modalities, capabilities, and supports_tool_calling to the Python IModel interface and implement them in Model / ModelVariant.
• Extend ModelInfo (Pydantic model) to parse the new metadata fields from get_model_list.
• Add Python tests validating the new properties are present and forwarded correctly (including via selected_variant).
