Runs Kyber outside Wolf so its embedded WebView2 can initialize without
nested-bwrap blocking CLONE_NEWUSER. Builds the Wine prefix, ensures the
WebView2 Evergreen runtime is installed (the component that intercepts EA's
qrc:// OAuth redirect), registers Kyber as a non-Steam shortcut forced to
Proton Experimental, and notes the Steam Remote Play path for headless boxes.
No fake cmd.exe / Firefox scaffolding needed here.
