- Add BgUpd + a day-one webview package to PRODUCT_PACKAGES so devices boot with a working WebView before bg-upd's first check ever runs - Add config_webview_packages.xml declaring the providers bg-upd can switch between at runtime - Add default_wallpaper.png to the framework RRO overlay (single image for all devices/densities for now — see the new overlay README)
