Patches the Electron asar bundle to inject setDisplayMediaRequestHandler with useSystemPicker: true, which routes screen capture through the native PipeWire/xdg-desktop-portal pipeline on Wayland. Based on upstream draft PR nextcloud/talk-desktop#1022. Uses the patched version in communication role.
