Third-party clients (Vertex, Bedrock) don’t support structured outputs and its beta header, so when the SDK sets it, the remote server returns
Error code: 400 - {'message': 'invalid beta flag'}.This change just avoids always setting that header, so we can still port the
tool_runnerandstreamhelpers, which useparsemethod internally, with minimal changes.
