Cerebras: Unsupported response_format type json_schema - name field required

# Cerebras: Unsupported response_format type json_schema - name field required

## What is going on

After upgrading to cerebras-cloud-sdk 1.16.0, using response_format with the json_schema type fails with: Unsupported response_format type: json_schema, code wrong_api_format. My schema itself looks valid. The same code worked before the upgrade, so something changed in how the SDK sends the format.

## What actually works

The error is because the name field is required for json_schema response formats. Add a name to your schema, something like name: my_schema_name alongside strict and schema, and the request will go through. Worth noting that json_schema support was pretty new around that SDK version, so the docs did not call out the required fields clearly.
