The underlying genai SDK supports a Labels field on GenerateContentConfig for billing attribution, request tracking, and Cloud Logging filtering. This was not exposed through the eino-ext Gemini wrapper. Add WithLabels() option that passes user-defined key-value labels through to the Vertex AI API on each GenerateContent request.
