feat: check for updates page in settings

Add a full-screen update checker accessible from a button at the bottom of the settings page. It queries the fork's GitHub latest release and can download + install the APK in place. - UpdateRepository (core/data): fetch releases/latest via GitHub API, parse tag/description/APK asset, stream APK download to cacheDir - VersionComparator (core/domain): compare 4.4.6-ba7opf.N style tags (base version first, then build number; v-prefix tolerant) + tests - IMainContainer/MainContainer: inject updateRepo - UpdateCheckerScreen (feature/settings): shows current version, checks for updates, displays latest version + release notes, and a Download & install button; FileProvider hands the APK to the system installer - SettingsScreen: bottom entry button, full-screen page toggle - AndroidManifest: REQUEST_INSTALL_PACKAGES permission + FileProvider - i18n strings (en/zh)
