protocol Added foreign-toplevel protocol integration for splash screens to make them visible and manageable in the dock. Splash screens now appear in the dock with proper identification and can be closed directly from the dock. When a splash screen is closed before the actual application window appears, the matching application window will be automatically closed to maintain consistency. Key changes: 1. Register splash screens with foreign-toplevel protocol to appear in dock 2. Implement splash screen closure handling via dock requests 3. Track closed splash appIds to close matching application windows 4. Move foreign-toplevel management from Helper to ShellHandler for better integration 5. Add proper splash screen identification and state management Log: Splash screens now appear in dock and can be closed via dock interface Influence: 1. Test splash screen visibility in dock for various applications 2. Verify splash screen closure from dock works correctly 3. Test that closing splash screen prevents matching application window from opening 4. Verify normal window behavior remains unchanged after splash integration 5. Check that skipDockPreView property still works correctly for all surface types 6. Test application launch with and without splash screen closure feat: 使闪屏通过foreign-toplevel协议在dock栏可见可关闭 为闪屏添加foreign-toplevel协议集成，使其在dock栏中可见并可管理。闪屏现在 会出现在dock栏中并带有适当标识，可以直接从dock栏关闭。如果在实际应用程序 窗口出现之前关闭闪屏，匹配的应用程序窗口将自动关闭以保持一致性。 主要更改： 1. 将闪屏注册到foreign-toplevel协议以在dock栏显示 2. 实现通过dock请求处理闪屏关闭功能 3. 跟踪已关闭闪屏的appId以关闭匹配的应用程序窗口 4. 将foreign-toplevel管理从Helper移动到ShellHandler以实现更好集成 5. 添加适当的闪屏标识和状态管理 Log: 闪屏现在可在dock栏显示并可通过dock界面关闭 Influence: 1. 测试各种应用程序的闪屏在dock栏中的可见性 2. 验证从dock栏关闭闪屏功能正常工作 3. 测试关闭闪屏后是否阻止匹配应用程序窗口打开 4. 验证闪屏集成后正常窗口行为保持不变 5. 检查skipDockPreView属性对所有表面类型是否仍正常工作 6. 测试在有和没有关闭闪屏的情况下应用程序启动行为
Reviewer's GuideIntegrates splash screens with the Treeland foreign-toplevel protocol so they appear and are controllable from the dock, centralizes foreign-toplevel handling in ShellHandler, and ensures that closing a splash from the dock prevents the corresponding app window from opening while keeping dock previews in sync with surface lifecycle and skipDockPreView state.

Hey - I've found 2 issues, and left some high level feedback:
- The new
SurfaceWrapper::requestCloseSplashis declared as a slot but used as a signal (e.g.connect(wrapper, &SurfaceWrapper::requestCloseSplash, ...)andQ_EMIT requestCloseSplash()), which will not compile with the new connect syntax; move it to thesignalssection instead ofpublic Q_SLOTS. - In
ForeignToplevelV1::addSurface, theset_identifiernow uses astatic int counterinstead of something tied to the underlying surface/handle; consider whether this needs to be stable/unique across the compositor lifetime and make the identifier generation more robust (and thread‑safe) if clients rely on it. - The
m_closedSplashAppIdsset is only pruned when a matching window appears; if an app never creates a window after its splash is closed, the appId will remain in the set indefinitely—consider adding a timeout or cleanup path to avoid unbounded growth over long sessions.

**issue (bug_risk):** requestCloseSplash should be declared as a signal, not a slot, to match its usage.
`requestCloseSplash` is currently under `public Q_SLOTS`, but in `surfacewrapper.cpp` you use `Q_EMIT requestCloseSplash();` and in `ShellHandler::createPrelaunchSplash` you connect with `&SurfaceWrapper::requestCloseSplash` as if it were a signal. Because it’s not declared under `signals:`, there will be no meta-object entry, so this pointer-to-member connection will fail at runtime (usually with `QObject::connect: No such signal ...`) and the handler won’t be invoked. Please move `requestCloseSplash` to the `signals:` section (or add one) and keep the implementation the same.

**issue (bug_risk):** m_treelandForeignToplevel is used from Helper but declared private, which will not compile.
In `Helper::init` you connect directly to `m_shellHandler->m_treelandForeignToplevel`, but this member is private in `ShellHandler` and `Helper` is not a friend, so this will not compile. Please either add a public accessor (e.g. `ForeignToplevelV1 *treelandForeignToplevel() const`) or route these connections via `ShellHandler` signals instead of accessing its internals directly.

Pull request overview
This PR integrates prelaunch splash screens into Treeland’s ForeignToplevelV1 (dock/preview) so they appear in the dock and can be closed from it, and moves Treeland foreign-toplevel registration responsibilities from Helper into ShellHandler for tighter lifecycle integration.
Changes:
- Register splash
SurfaceWrapperinstances withForeignToplevelV1, including basic metadata and close handling. - Centralize Treeland foreign-toplevel surface registration in
ShellHandler, including reacting toskipDockPreViewchanges. - Track appIds for splash screens closed from the dock and close the matching real toplevel when it appears.

本 PR 将预启动闪屏接入 Treeland 的 ForeignToplevelV1（dock/preview 协议）以便在 dock 中可见并可关闭，并将 Treeland foreign-toplevel 的管理从 Helper 迁移到 ShellHandler，以获得更一致的生命周期与状态联动。
主要改动：
- 将闪屏
SurfaceWrapper注册到ForeignToplevelV1，并支持从 dock 发起关闭。 - 在
ShellHandler中集中处理 Treeland foreign-toplevel 的注册/反注册（随skipDockPreView动态变化）。 - 记录从 dock 关闭的闪屏 appId，并在真实窗口出现时自动关闭匹配窗口。

**issue (bug_risk):** requestCloseSplash is declared but not defined, and is used like a signal, which will currently fail to link/work correctly.
In `SurfaceWrapper`, `requestCloseSplash` is declared as a slot in the header but never defined in the `.cpp`, while `ShellHandler::createPrelaunchSplash` connects to `&SurfaceWrapper::requestCloseSplash` and `SurfaceWrapper::close()` emits it. This will cause a linker error and, since it’s in `public Q_SLOTS` instead of `signals`, moc won’t treat it as a signal. If this is meant to be a signal, move it to the `signals` section and let Qt handle it as a signal (no manual implementation needed). If it’s meant to be a slot callable from QML, add a definition and consider renaming to clearly distinguish the signal from the slot.

In the header, `ShellHandler` declares `void setupDockPreview(QObject *dockPreview);`, but `shellhandler.cpp` only defines `void ShellHandler::setupDockPreview()` (no parameter) and uses `m_dockPreview`. This API mismatch will either produce a linker error if `setupDockPreview(QObject*)` is called, or indicates a stale declaration.
Please either remove the parameterized declaration and keep the no-arg version as a private helper/slot, or update the implementation to take the `QObject *dockPreview` parameter and pass it from callers instead of using `m_dockPreview` directly.
