ws01图床 - 基于Cloudflare的 R2 云存储
步骤一（在 Cloudflare Dashboard 中完成，适合 UI 操作）：
1、创建 R2 Bucket：进入 Workers & R2 → R2 → Create bucket，记住 bucket 名称。
2、创建 KV 命名空间：Workers → KV → Create namespace，记下命名空间 ID。
3、创建 Worker：Workers → Create a Worker，新建或编辑现有 Worker。
在 Worker 的 Settings → Variables & secrets 中添加绑定：
（变量名1）：R2BUCKET，（变量名2）：KVSTORE，（变量名3）：ADMIN_PASSWORD：设置为强随机密码
新增 JWT_SECRET 并在代码中替换签名密钥（提高安全性）。
