        Encode container_id in response object with provider/model metadata for routing.

        This mirrors the responses API pattern where response IDs are encoded with
        routing metadata so follow-up calls can route to the correct provider.

        Encodes when:
        1. litellm_metadata contains model_info.id (indicating router/proxy usage), OR
        2. extra_body contains target_model_names (indicating model-specific routing)
