09-editor — 自定义编辑界面

"Sometimes it's hard to describe what you want in a text box. Ask for a throwaway editor for the exact thing you're working on — and always end with an export button that turns whatever you did in the UI back into something you can paste into the agent or commit."

核心约束（不可妥协）

每个 09-editor 范式产出的页面必须有"复制结果"按钮。 让用户在 UI 里的所有操作能 → 一段可粘贴的文本 → 回到 agent。

没有 export 出口的"编辑器" = 玩具，不是工具。
