/**
 * Gemini HTTP Provider (V2)
 *
 * 以 Gemini Chat 协议（gemini-chat）为目标，调用 Google Generative Language API。
 * - 默认基地址：https://generativelanguage.googleapis.com/v1beta
 * - 生成路径：/models/{model}:generateContent
 * - 认证：优先使用 header 'x-goog-api-key: <API_KEY>'；若仅提供 Authorization: Bearer <key>，自动转换为 x-goog-api-key。
 * - 形状转换：由 GeminiProtocolClient 统一处理（OpenAI Chat → Gemini contents/systemInstruction/generationConfig）。
