概述
对 @like147222 (小飒) 开发的 GPTImageGen 插件进行鲁棒性增强和文档完善，从 v1.0.0 升级到 v1.1.0。
原始插件由小飒开发，本次改进由 infinite-vector 完成，已获得小飒授权。
改动内容
🔒 安全性
修复源码中
OPENAI_BASE_URL
默认值硬编码为开发用反代地址的问题，改为
https://api.openai.com
🔄 稳定性
新增
httpRequestWithRetry()
包装器，对 429 (Rate Limit) 和 503 (Service Unavailable) 自动指数退避重试
重试次数和基础延迟可通过
MAX_RETRIES
/
RETRY_BASE_DELAY_MS
环境变量配置
✅ 正确性
图生图输入图片新增 4MB 大小校验（OpenAI /v1/images/edits 端点限制），支持 data URI / URL / 本地文件三种来源的校验
纯数字 size 参数自动兼容（如
1024
→
1024x1024
），防止用户配置错误
🎨 兼容性
downloadImage()
现在返回
{data, contentType}
而非裸 Buffer
saveImageToLocal()
根据 Content-Type 推断扩展名（jpg/webp/gif/png），不再硬编码 .png
新增
inferImageExtension()
统一扩展名推断逻辑
📝 文档
plugin-manifest.json
更新：author、version、configSchema（改为带 description 的对象格式）
invocationCommands 描述补充：quality 各档位说明、transparent 背景限制、4MB 图片限制、版本快照用法、重试机制说明
测试
✅ 文生图 (GPTGenerateImage) 测试通过
✅ 图生图 (GPTEditImage) 测试通过（本地文件路径输入）
✅ 插件热重载后正常加载
