Move a lot of the installation work to be done during the first phase of installation (when possible), before the target app needs to be terminated. For the common case where the old and new bundles are on the same volume, the final phase of installation requiring a restart is now just an atomic swap.
Also move the termination listener to the agent app which resolves some launch/CI failures we've been seeing.
If the app termination request is delayed or canceled, the user can check for updates again with the standard user driver and try installing/relaunching again, which will trigger the installer to send another quit event to the running application.
Before the install/relaunch window would close but the check for updates option would still be present but not functional.
