/**
 * 素材删除流程的定向用例。
 *
 * 这条流程从「编辑素材标签」面板抽成了 `useResourceAssetDeleteFlow`，改由资源卡选中工具条
 * 的「删除素材」触发；判据与实现在抽前后必须逐字不变 —— 所以这里钉住的是三件事：
 * 1. 点入口只读引用、只开二次确认面板，不直接删；
 * 2. `deleteReferencedVersions` 的三分支（不勾 / 勾 / 未被引用）；
 * 3. 失败时既不改状态也不静默：原因经宿主的 `onError` 出口出去。
 *
 * 工具条上的入口渲染判据（只有 `manifestAssetId` 存在才渲染）与真链路 IPC 载荷由
 * `resourceVersionReplacement.test.tsx` 的工台用例覆盖，这里只测流程本身。
