feat: 与我相关重构 — workspace-engine 聚合引擎

架构：新建 lib/workspace-engine.ts
- aggregateWorkItems(): 从所有 store 统一聚合"与我相关"数据
- 每个 WorkItem 包含：type, title, status, completed,
  productName, projectName, versionName, versionId
- 新增模块只需在引擎中添加聚合逻辑，工作台自动展示
- 解决了之前各模块增加内容但工作台无法关联的问题

功能改动：
1. 每个任务显示完整上下文：产品 / 项目 / 版本
2. 版本名可点击跳转到版本详情
3. 所有任务（含已完成）统一展示，已完成半透明+绿色勾
4. 左侧增加"显示已完成"开关
5. 待办/已完成计数统计
6. 统一卡片样式：类型标签 + 状态 + 编号 + 标题 + 优先级
7. Bug 额外显示严重程度标签
8. 列表默认排序：未完成在前，已完成在后
