name: Plugin Registry

# 插件市场：plugins/registry/<id>.toml 指向作者仓库的固定 commit。
# - check：PR 上运行作者的代码（测试、pnpm 构建），只读权限、不读 secret。
#   检查脚本与 ab_sdk 取自 base 分支，PR 不能改掉检查规则。
# - plan / build：合并后。build 每个插件一个 job（会运行作者的前端构建，没有密钥），
#   一个插件的构建篡改不到别的插件。
# - sign：唯一读 PLUGIN_SIGNING_KEY 的 job，不运行作者代码。它自己下载复用的 zip
#   并校验 sha256，核对每个新 zip 的 id 与来源，再签名发布。
