 当前发布目标固定为 Windows x64 NSIS。执行 `npm run ai-game-creator-shell:build` 会向 Tauri 传入 `--target x86_64-pc-windows-msvc`，在构建完成后自动扫描 `.exe` 安装包，并在 `apps/ai-game-creator-shell/src-tauri/target/x86_64-pc-windows-msvc/release/bundle/latest.json` 生成包含版本、下载地址、大小和 SHA-256 的清单。可通过 `AGC_BUILD_TARGET` 显式覆盖目标（发布仍应使用 Windows x64），通过 `AGC_UPDATE_ARTIFACT` 指定要发布的安装包，通过 `AGC_UPDATE_OSS_BASE_URL` 指定 OSS 前缀，通过 `AGC_UPDATE_RELEASE_NOTES` 写入发布说明；`--no-bundle` smoke 构建不会生成清单。
 
 每次发布安装包上传完成后，再上传同一目录生成的 `latest.json`，确保 `downloadUrl` 指向已存在的 OSS 对象；清单和安装包均使用公开可读对象，不在清单中保存凭据、签名或本地路径。构建脚本不自动上传 OSS，避免把 AccessKey 写入本地配置或 CI 日志。
+
+如需一键构建并上传，可执行 `npm run ai-game-creator-shell:release:upload`。该命令要求本机已安装并配置 `ossutil`，先构建 Windows x64 NSIS，再上传安装包和 `latest.json`。默认上传到 `agc-dev` / `oss-rg-china-mainland.aliyuncs.com`，也可用 `AGC_OSS_BUCKET`、`AGC_OSS_ENDPOINT` 和 `OSSUTIL_BIN` 覆盖；凭据由 ossutil 本机配置读取，不能写入仓库或命令行参数。
