Enumerating Vulkan adapters crashes inside Intel's igvk64.dll on some UHD
Graphics drivers, before any Rust error handling runs. Since #22 the
Windows instance is DirectX 12 only; this keeps Vulkan out of every
default path and adds two fallbacks so DX12-only can't leave a PC without
a window:
- A DirectX 12 probe before eframe starts: no hardware adapter that meets
eframe's limits -> OpenGL (plus DX12/WARP as last resort when WARP is
all DX12 offers).
- If run_native fails with a wgpu error before the app was created, start
once more with the other of DX12/GL (eframe reuses its event loop).
WGPU_BACKEND still overrides everything, and nothing else is tried then.

UiState gains interfaceScale (percent, 100 = Auto, 75–200), saved in
ui.json and applied as egui's zoom factor on top of the desktop scale.
New UI command view.interfaceScale {percent | "auto"} clamps hostile
values; a malformed saved value reads as 100. View tab gets an
"Interface size" picker. egui's built-in keyboard zoom is turned off so the
preference owns the zoom.
