背景

跟进已合并的 #263 中的 两条 P2 review 意见。原修复覆盖了 More 浮窗退出时，主窗口上账户选择器交互转场的窗口生命周期；后续审查指出 interactiveCoordinator(in:) 只查看根控制器及 presentedViewController 链。UIKit 文档说明，transitionCoordinator 会向父控制器回退，但根控制器不会因此自动看到其子控制器的交互转场。已挂载的子 UINavigationController 若正在交互式 pop，旧实现可能提前释放退出浮窗的 window context。

另一个意见涉及 NativeList 视频首帧测试：若中间的 XCTUnwrap 提前抛错，末尾的 recycle() 不会执行。现有容器移除和对象析构仍有取消路径；本 PR 将测试中的显式清理改为 defer，保证各退出路径一致，不将其描述为已证实的生产资源泄漏。

改动

• 保留原有根控制器、presented 链的优先查找顺序，同时遍历视图已加载且挂载在同一 App window 的 contained children。使用栈与 identity 集合，避免重复遍历，也不会为了检查离屏子控制器而加载其 view。
• 沿用 fix: retain iOS overlay window during interactive dismissal #263 的 retired window token、交互完成或取消回调、下一主线程轮次重查与 scene disconnect 清理；本次不改公开接口、Android/Web 或业务调用。
• NativeList 测试对两个 preview slot 分别使用 defer recycle()；保留测试缓存复用所需的中途 recycle() 以及全部原断言和等待期限。
• 更新 NativeOverlay SPEC 的子控制器边界及测试范围。

验证

• 在旧版 WindowManager 源码上运行真实 UIKit fixture：普通根控制器包含子 UINavigationController，启动百分比驱动的交互式 pop；确认交互仅出现在 child，旧版恰在“退出窗口应保留”的断言失败。
• 同一 fixture 在本 PR 源码上通过：子导航交互期间保留旧窗口，取消后释放。另有负例确认未加载或未挂载的 child 不会触发保留，也不会加载 view。
• 聚焦 iOS 27 模拟器原生 harness：13/13 通过。原有受控 transition coordinator 测试覆盖完成、取消、owner 重开与 scene 断开；新增真实 UIKit 用例只覆盖 contained navigation 的取消路径。
• NativeList 测试文件通过 Swift 语法解析，git diff --check 通过。本 PR 的 hosted CI 已全部通过，包括 ios-native、ios-xctest 和 device-utils-store；视频首帧用例实际通过（3.445 秒），NativeList XCTest 套件为 95 项、1 项既有跳过、0 失败。此前 fix: retain iOS overlay window during interactive dismissal #263 的 hosted CI 和录屏不作为本 PR 新增 child 路径的验证证据。

#263 的修复前后录屏记录的是账户选择器主窗口交接，并非本 PR 新增的子导航路径。这里的真实 UIKit 验证仍限模拟器；真机和更广的应用场景尚未验证。本 PR 不发布 SDK，也不合并应用侧更改。

独立复核已核对本次源码、真实 UIKit 红/绿结果及线上差异。Devin 的检查状态为通过，但其完整审查因额度不足而跳过，不计作额外审查证据。
