Download a signed URL

Download a signed URL

curl -sL -o image.png "https://private-user-images.githubusercontent.com/..."

The key insight: `application/vnd.github.full+json` returns `body_html` containing JWT-signed URLs for private image attachments. These URLs expire after ~5 minutes.
curl -sL -o image.png "https://private-user-images.githubusercontent.com/..."

核心原理：`application/vnd.github.full+json`会返回包含JWT签名URL的`body_html`，这些URL用于访问私有图片附件，有效期约5分钟。
