Some checks failed
CI / check (pull_request) Failing after 2m14s
根因：RouteKeeper 保活缓存了首页 index 节点，DefaultRoute 中的声明式 <Navigate> 会随缓存节点在后续路由变化时反复触发 replace，导致所有导航 被强制拉回落地页（dashboard），刷新后因不再经过 / 而恢复正常。 修复：DefaultRoute 改为 effect 导航，仅在确实处于 / 且已算出落地页时 跳转一次；navigate 通过 ref 持有避免 effect 空转。新增集成测试覆盖 「首次进入 / → 跳转一次 → 后续导航不被劫持 → 回到 / 仍能重定向」。
