编辑图像（OpenAI 兼容）
接受 multipart/form-data（带参考图）或 JSON。计费单位取决于模型，以模型目录页标注为准。
xai/grok-imagine-image-2.0：源图用 JSON image（{"url": ...}，https URL 或 data URL）传一张，或用 JSON images 传最多 3 张，也可用 multipart 的 image / image[]。多张图时在提示词里用 <IMAGE_0>、<IMAGE_1> 依次指代。编辑时 quality 缺省为 medium（auto 即 medium）；resolution 与 n 同生成接口，不支持 mask。按输出张数、随质量 × 分辨率计费，每张源图每次请求另收一次。源图超过 3 张在计费前返回 400。

TypeScript Definitions
Use the request body type in TypeScript.
Request and response bodies match the upstream provider's official format verbatim —
RouteMux passes them through untouched. See the provider's own docs for field definitions;
the gateway itself only reads model and stream.
