 `.woodpecker/ci.yml` 在 push 和手动运行时执行 API 契约、Core、Web、服务端检查；每次 push 都会构建前端。`.woodpecker/release-backend.yml` 响应 `vMAJOR.MINOR.PATCH` SemVer tag；也可手动运行并传入 `RELEASE_TAG`(例如 `v0.1.0`)。测试通过后用 Linux native agent 的 Buildah 构建并推送同名后端镜像 tag。两者都通过 Woodpecker secret `gitea_clone_webdrop` 从 `https://git.oeo.one` 克隆公开仓库。

 后端镜像发布到 `zot.oeo.one/justme/webdrop-api`。Woodpecker Linux agent 通过内网 `192.168.2.162:5000` 访问同一 Zot 仓库，发布需要 Buildah 与 tag/manual 事件可用的 secrets `registry_username`、`registry_password`。使用已发布镜像时，在 `.env` 中设置 `WEBDROP_IMAGE_TAG`，仓库名已填入 `.env.example`。
