fn install_update(&self, package_path: &Path) -> Result<(), PlatformError>

Requests installation of an application update from a local package file.

This launches the system installer and returns once the request is issued. It does not guarantee the update is installed successfully.

Platform Support / Notes

• Android: Launches the system installer; requires user confirmation. Requires REQUEST_INSTALL_PACKAGES and a FileProvider for APK sharing.
• macOS: Planned support for .pkg/.dmg installers.
• iOS: Not supported (App Store only).
• HarmonyOS: Not implemented (returns error).
