Update with recovered code from VM binaries (Jan 1)
Recovered from decompiled OpenMaui.Controls.Linux.dll: - SkiaShell.cs: FlyoutHeader, FlyoutFooter, scroll support (918 -> 1325 lines) - X11Window.cs: Cursor support (XCreateFontCursor, XDefineCursor) - All handlers with dark mode support - All services with latest implementations - LinuxApplication with theme change handling
