+/**
+ * acr workflow export <name> / acr workflow import <file> — workflow 可攜原語（t158）。
+ *
+ * leo 07-31 定調：「你要做的就是一個叫 export，另一個是 import，打包好的幾個工作流
+ * 準備好直接 import 就好了。現在如果我要把我做的工作流分享給同事，我要怎麼 export？
+ * 他要如何 import？是缺了功能用 search 來湊嗎？在從前就是寫成幾個 yaml 丟過去
+ * 讓新的送進 KBDB 不是嗎？」
+ *
+ * - export：GET /webhooks/named/:name/definition → 寫成 .workflow.yaml 可攜檔
+ *   （name/description/flow[從 graph.edges 反推，供人讀]/config/graph[可執行形，引擎產]）。
+ * - import：讀可攜檔 → **直接 POST /webhooks/named**。零編圖、零 /cypher/search、
+ *   零存在性驗證（部署≠發現，V2 純複製）——缺件的 workflow 照樣進，跑錯再改。
+ *   手寫的 yaml（無 graph 欄）請走 acr push（那條才需要編圖）。
+ * - 安裝器走同一條路：workflows.json 打包期預編 graph，pushWorkflow 直接 POST——
+ *   不准安裝器走私有路徑。
