 - Test: `src/__tests__/opencode_cell_actions.spec.ts`(新建)

 **Interfaces:**

 - Consumes: `callOpenCodeEdit(request, serverSettings)`(来自 `../api/opencode_client`,不变);`extractCellContext(cell, notebookPanel)`(来自 `../context/cell_context`,不变);`../types` 全部类型(不变)。
 - Produces: `class OpenCodeCellActions extends Widget`,构造函数 `constructor(cell: CodeCell)`;`setOpenCodeRuntime(args: { settings: OpenCodeSettings; serverSettings: ServerConnection.ISettings }): void`;CSS 类 `opencode-cell-actions` / `opencode-btn opencode-btn-{optimize|fix|edit}`。Task 2 的 index.ts 依赖这两个导出。

 **Files:**

 ## 已确认的决策
 
-| 问题 | 决策 |
-|---|---|
-| 可见性语义 | 跟随原生 toolbar:只在 **active cell** 右上角显示(与上移/下移按钮行为严格一致) |
-| 底部 footer | **删除**,三个按钮全部上移 |
-| 点击交互 | 本次不变:`🪄 编辑` 仍用 `window.prompt`;结果仍走 `Notification`;inline prompt box / diff 面板留待后续 |
-| 作用范围 | 仅 `CodeCell`;Markdown 等 cell 不显示 AI 按钮(现状 footer 挂在所有 cell 上,属顺带修正) |
