[Windows] Verify: events, input and icon reports from window_manager #78
Description
These were reported against window_manager 0.5.x, whose platform code is gone: window_manager 0.6.0 is rebuilt on nativeapi. None of them has been checked against nativeapi yet. Each needs a reproduction with nativeapi (a Flutter app on the Window API), then a fix or a note that it no longer happens. Tick them off here as they're checked.
- [Windows]: Resize event not fired when window snapping leanflutter/window_manager#207: resize event not fired for snapping (Win+Arrow, Windows 11 snap layouts, double-click on the title bar)
- Incorrect behavior of
onWindowBlurleanflutter/window_manager#294: blur event reported when a minimized window is restored, instead of focus - [Windows] First Enter and Escape key is eaten after hide/minimize the app via code leanflutter/window_manager#480: first Enter/Escape key swallowed after hiding or minimizing from code and showing again
- Windows platforms do not support a maximize call in onDoubleTapDown leanflutter/window_manager#511: maximize() doesn't work while the mouse is captured (called from onDoubleTapDown)
- 屏幕像素比导致初始化差异从而导致 overflowed 警告 leanflutter/window_manager#245: moving between monitors with different scale factors changes the window size and causes overflow
- setIcon没有生效 leanflutter/window_manager#534: setIcon() has no effect (Windows 11); check

Replayed with the real nativeapi Flutter Window API in a real Flutter Windows app (Windows 11 build 26200, Flutter 3.47.6 debug):
tools/gui/flutter_window_reports_test.ps1builds the fixturetools/gui/window_reports_flutter.dartagainst the workspace's Dart packages, paints solid colours, and measures native geometry, styles, DWM caption buttons, pixels and frame-by-frame samples. No keyboard input; the only clicks are owner-guarded ones on the app's own window. The suite passes repeatedly on core 9d6b50d (workspace libnativeapi/nativeapi@2894880).Focused, notBlurred.ResizedandMaximized; another restores withResizedandRestored. (Win+Arrow and the snap-layout flyout need keyboard input or clicks outside the app, not driven.)maximize()fromonDoubleTapDown, with the pointer still down and captured (real double-click on a Flutter area): maximizes.Application::SetIconset the class icon ofGetConsoleWindow(), which a GUI app does not have, and widened the UTF-8 path byte by byte — it returned true and changed nothing. It now loads the big and small icon and sets them on every top-level window of the process (false without one). From Flutter with a path insideflutter_assets: the window's icons change. Core testapplication_icon_windows_test(non-ASCII path, sizes, replacing, refusals).Not covered: #480 (needs keyboard input) and #245 (needs two monitors with different scale factors, as #63). Keeping this open for those.
