新增: 灵感归档箱与任务归档动线

- ideasStore/taskStore: archiveIdea/archiveTask IPC 封装(本地移除/本地更新,对齐 delete 语义)
- project.ts 组合 store 显式透传 archiveIdea/archiveTask
- Ideas.vue: 筛选栏归档箱 Tab(独立数据源 ideaApi.listArchived,主查询不受扰);archiveCurrentIdea 处理器(归档确认+归档箱内取消归档自动清选中);IdeaDetail 传 in-archive-box prop
- IdeaDetail.vue: inArchiveBox prop + archive emit;操作区归档/取消归档按钮,归档箱模式隐藏删除(防误删归档记忆)
- i18n zh-CN/en ideas 补 filterArchived/archiveBoxEmpty/quickArchive/quickUnarchive/confirmArchive/toast 键(前批遗留)
验收: vue-tsc --noEmit EXIT 0
