     * @param {string} body.prompt - Free-form instruction for Gemini (e.g. "Summarize this video", "What products appear?")
     * @param {boolean} [body.highQuality] - Use gemini-3.1-pro-preview instead of flash. Default: false.
     * @param {string} [body.mimeType] - MIME type hint (e.g. "video/mp4"). Auto-detected if omitted.
     * @returns {Promise<TotalumApiResponse<GeminiAnalyzeVideoResponse>>} - The Gemini response with the model used and candidates
