Full Release Notes

## 🚀 新增内容

3. OSS 适配器支持 `IStorage` 契约中的字符串上传，并在无法覆盖响应 `Content-Type` 的 OSS 场景下沿用对象原始类型。
4. COS 适配器对缺失对象下载进行预检，确保符合统一下载错误契约。

## 🐛 修复

1. 修复阿里云 OSS `getObjectMetadata` 从错误字段读取 ETag，导致 ETag 缺失并触发下游元数据校验失败的问题。
2. 修复 S3/MinIO 源文件不存在时 API 返回 `Unknown` 的问题，改为返回文件找不到并使用 HTTP 404。
3. 修复旧插件节点升级后输入框消失的问题。
4. 修复头像 URL 被重复编码的问题。

## 🛠️ 代码优化

1. S3 SDK 增加跨 MinIO、AWS S3、Cloudflare R2、OSS 和 COS 的通用集成测试，覆盖 private/public bucket、公开 URL 和预签名 URL 的真实访问。
