评审后续：修正标题栏项目标签的空态、视图门控与文案

- 面板形态：快照读取成功但没有在跑回合时不再渲染「未能读取正在运行的项目」，补回 !readFailed 守卫
- 发布门控：currentProjectPath / currentProjectName 只在 launcherView === 'project-development' 时发布，离开工作台按口径回落到最近启动的在跑项目
- 菜单头部只报运行中数量，读取失败结论由 role=status 一行独占，避免同一句连排两遍
- 标签提示拆成「作用域 + 运行状态」：回落态记为「最近运行的项目：X」、状态位「共 N 个项目在运行」，不再重复「正在运行」
- 数量徽标补 title 说明数字含义
- 用例：新增面板空态回归与两条视图门控回归，更新两处标签断言；三条定向文件 25 passed
- 文档：决策日志补 2026-10-05 评审后续条目并修正实施计划交叉引用，里程碑补 2026-10-05 修订，实施计划与主规范同步口径
