感谢贡献！Workflow Center 是一个有趣的方向，但目前暂时不合并，主要原因：

1. 缺少 Rust 后端实现：PR 只实现了 Web 模式（dev-api.js），桌面端（Tauri）完全没有对应的 Rust 命令实现，意味着桌面用户无法使用该功能
2. 没有执行引擎：节点类型定义了 9 种，但实际的工作流执行逻辑未实现，只有 CRUD 和状态管理的壳
3. 上游依赖：工作流执行需要 OpenClaw 上游支持（调度、状态机、任务编排），目前上游没有这个能力
4. 核心文件改动风险：PR 修改了 sidebar.js、main.js、 auri-api.js 等核心文件，合并冲突和维护成本较高

如果后续 OpenClaw 上游增加了工作流引擎支持，我们会重新评估这个功能的集成方案。届时欢迎再次参与讨论。
