Summary

On Windows, if a satellite is torn off and the main window is then minimized and restored, the satellite comes back all white until the pointer passes over it.

• Cause: minimizing a window hides the windows it owns (satellites, dialogs), and restoring it shows them again via WM_SHOWWINDOW / SW_PARENTOPENING, without TaoWindow.show() ever running. As a result, showHook never arms forcePresentOnce. DWM has dropped the hidden window's frame and the scene is clean, so no present happens.
• Fix: the deco WndProc arms a flag on SW_PARENTOPENING. Once the window is really mapped (WM_WINDOWPOSCHANGED + SWP_SHOWWINDOW), it calls NativeTaoWindowsDecoBridge.onShownWithOwner, and the scene host then forces its next present. Calling back from WM_SHOWWINDOW itself is too early: the window is still hidden and DWM drops that present too (measured: still white).
• onShownWithOwner is declared in the reachability metadata, so the upcall survives native image.
• This covers every owned window (dialogs of a minimized window included), not just satellites.

Test plan

• New headful case windows a satellite is painted after its parent is restored (SatelliteRestorePaintHeadfulCases): 3 minimize/restore rounds, reading the satellite back through PrintWindow (DWM's copy) without moving the pointer
  • without the fix: #FFFFFFFF, 0% of the content visible
  • with the fix: 100%, on all 3 rounds
• Neighbouring satellite headful cases (anchor/follow, hide while maximized) still pass
• ktlintCheck + detekt clean
• Manual check in the Lab: tear off a satellite, minimize, restore
