Version: 0.9.79.dev.260506

后端：
1. 本地后端启动体系收口到 `backend/scripts`，移除 `cmd/all` 聚合入口，并将仓库根兼容启动语义收敛为 `StartAPI` 别名；新增 dev-up / dev-down / services-up / services-down / dev-status / dev-logs / service-restart 脚本，统一托管多服务进程、日志、PID 与基础设施启动。
2. 课表服务超时口径统一放宽到 5 分钟，覆盖 gateway / client / rpc server / config example，避免课表导入与图片识别在长耗时场景下被内层提前截断。
3. `today` 课表查询修正为读取真实当前日期，不再使用硬编码测试日期；同时剔除旧缓存与返回结果里的 `empty` 占位事件，后端只返回真实日程，空档改由前端时间轴自行补齐。

前端：
4. 首页路由切回改为复用 `DashboardView` 实例，补 `keep-alive`、`onActivated` 与双帧缩放重算，修复从侧栏返回首页时首帧布局放大与重复加载闪动问题。
5. 首页加载态与今日时间线口径收口：移除额外 800ms `pageLoading` 人为延迟，task / schedule 改为分开驱动；时间线忽略 `empty` 事件，并统一空档文案为“无课”。
6. 收敛助手页与首页若干进场/弹性动画，降低结果卡片、微调弹窗、思考区与面板切换时的抖动感。

仓库：
7. README 补充后端本地快速启动说明，`.gitignore` 忽略 `backend/.dev` 脚本运行态产物。
