name: 桌面客户端发布

# 触发方式: 手动 (workflow_dispatch)。
# 在 GitHub Actions 页面点 "Run workflow", 选择要构建的平台 + 版本号,
# 构建完成后自动创建/更新 Release 并上传安装包。
#
# 为什么不用 tag 自动触发:
#   - 多平台并行构建, mac/linux 未就绪时会自动失败污染 Release
#   - 手动触发可精确控制 "今天只发 Windows, 明天补 mac"
#   - 版本号通过 input 传入, 与 tag 解耦, 更灵活
#
# 使用:
#   gh workflow run release.yml -f version=v0.2.0 -f platforms=windows
#   或 GitHub 网页 Actions → 桌面客户端发布 → Run workflow

            ### 下载
            选择对应平台的安装包, 解压后双击运行:

            | 平台 | 文件 |
            | :--- | :--- |
            | **Windows** | `TickFlowStockPanel-win-x64.zip` → 解压运行 `TickFlowStockPanel.exe` |
            | **macOS** | `TickFlowStockPanel-macos.zip` → 解压后右键打开 (绕过 Gatekeeper) |
            | **Linux** | `TickFlowStockPanel-linux-x64.tar.gz` → 解压运行 |

            ### 说明
