Background
Follow-up to #12252 (which added Gemini image generation to the
googleprovider). This wasn't yet wired up for thegoogle-vertexprovider.Summary
google-vertex'sgenerateImage(). When agemini-*model ID is detected, the image model internally delegates toGoogleGenerativeAILanguageModelwithresponseModalities: ['IMAGE'], matching the approach used in thegoogleprovider. Existing Imagen model behavior is unchanged.generateImagecapability forgoogle-vertexgoogleandgoogle-verteximage models to usesatisfies GoogleLanguageModelOptionsManual Verification
