v4.3.1: render Windows through wgpu and keep the installer window open

Windows 10 1809 sessions with only the Microsoft display driver expose OpenGL 1.1, which egui_glow refuses. The Windows build now uses wgpu on Direct3D 12 and its adapter selector accepts WARP, the software rasterizer, after every hardware class, so a VM or Remote Desktop session still starts. Linux keeps the smaller glow renderer.

The GUI is a windows-subsystem binary now, so launching it from the Start menu does not flash a console; startup failures and --help go to a native message box. The PowerShell installer pauses before closing unless -NoPause is passed.
