          ## 发布概览
          本次发布提供 SnowLuma 的 Windows x64 / Linux x64 / Linux arm64 构建产物，默认包含 WebUI。

          ## 下载说明
          命名约定：
          - 无后缀 \`.zip/.tar.gz\`：完整版本，内置 \`node\`/\`node.exe\` 与运行时依赖，解压即可使用。
          - \`-lite\` 后缀：精简版本，不含 Node.js 运行时，需自行安装 Node.js 22+。

          Windows：
          - \`SnowLuma-${tag}-win-x64.zip\`
          - \`SnowLuma-${tag}-win-x64-lite.zip\`

          Linux x64：
          - \`SnowLuma-${tag}-linux-x64.tar.gz\`
          - \`SnowLuma-${tag}-linux-x64-lite.tar.gz\`

          Linux arm64：
          - \`SnowLuma-${tag}-linux-arm64.tar.gz\`
          - \`SnowLuma-${tag}-linux-arm64-lite.tar.gz\`

          ## 更新内容
          ${changes}

          ## 使用说明
          - Windows x64：\`launcher.bat\` 或 \`node index.mjs\`。
          - Linux：\`./launcher.sh\` 或 \`node index.mjs\`。
          - 所有压缩包均已内置 WebUI 静态资源；启动后访问 http://localhost:5099。
          - Linux 版本仅提供 OneBot 桥接能力，NTQQ 进程注入仅在 Windows 下生效。

  # Triggers the Docker image build on SnowLuma.Docker.Framework once the
  # GitHub Release (and its per-arch tarballs) is published, so the Docker
  # workflow can pull the matching `SnowLuma-<tag>-linux-<arch>-lite.tar.gz`
  # asset and bake it into the container.
  #
  # Chained as a job dependency rather than via `on: release: published`
  # because workflows triggered by GITHUB_TOKEN cannot fire downstream
  # workflow events (GitHub anti-loop safeguard). Doing it as `needs: release`
  # keeps the dispatch under our PAT.
