/**
 * @fileoverview Client for interacting with the Google Gemini API.
 *
 * This module provides a comprehensive client for interacting with Google's Gemini AI models.
 * It handles API key management, model selection and fallback, request formatting, response
 * processing, rate limiting, error handling, and cost estimation for code reviews.
 *
 * Key features:
 * - Automatic model selection with fallback to alternative models
 * - Support for both streaming and non-streaming responses
 * - Robust error handling and rate limit management
 * - Mock response generation for testing without an API key
 * - Cost estimation for API usage
 * - Support for different review types (quick fixes, architectural, security, performance)
 *
 * The client prioritizes the latest Gemini models but includes fallback options
 * to ensure reliability even when specific models are unavailable.
