Ollama's `format` param only accepts '', 'json', or a JSON-schema dict, so
passing a Pydantic model class (the form OpenAIChatClient/FoundryChatClient and
create_harness_agent plan mode use) raised a ValidationError while building the
request. Convert a model class to its JSON schema when mapping response_format
-> format, keeping the original class for typed response parsing.
