fix(electron): force XWayland for Hyprland/Wayland compositors

Hyprland uses a custom Wayland compositor that is incompatible with
Electron's native Wayland backend. The window flickers because
Hyprland tries to apply entrance animations to a Wayland-native
Electron surface that keeps resizing during initial page load.

Force XWayland via two mechanisms:
- --ozone-platform=x11 (Chromium backend)
- ELECTRON_OZONE_PLATFORM_HINT=x11 (Electron runtime)

This makes Electron run through XWayland on Hyprland, which is
fully stable and eliminates the flickering.
