# 生成并签名一个镜像的发布清单：ci/release-manifest.sh <组件> <镜像仓库> <digest> <tag> <通道> <输出目录>
|
||
# 签名私钥从环境变量 RELEASE_SIGNING_KEY（PEM 内容）读取，只写进一个 600 权限的临时文件，用完即删；私钥只放在 CI 密钥里，不进仓库、不上传面板。
|
||
# 换发布密钥：把新公钥（PEM）放进环境变量 RELEASE_NEXT_KEY，清单里就会带 "next_key"（SPKI DER 的 base64）；这份清单仍由旧密钥签名，
|
||
# 宿主机更新器验过之后改认新密钥。下一个版本起把 RELEASE_SIGNING_KEY 换成新私钥、去掉 RELEASE_NEXT_KEY，并把安装脚本和 release-key.pub.pem 里的公钥换成新的。
|

# 输出：<输出目录>/manifest.json（扁平 JSON，签名对象是它的原始字节）和 manifest.sig（base64 的 DER ECDSA 签名）。
