…macOS The previous squirrel.mac patch cleaned up all staged update directories before starting a new download. This kept disk usage bounded but broke quitAndInstall() if called while a subsequent checkForUpdates() was in flight — the already-staged bundle would be deleted out from under it. This reworks the patch to read ShipItState.plist and preserve the directory it references, deleting only truly orphaned update.XXXXXXX directories. Disk footprint stays bounded (at most 2 dirs: staged + in-progress) and quitAndInstall() remains safe mid-check. Also adds test coverage for the quitAndInstall/checkForUpdates race and a triple-stack scenario where 3 updates arrive without a restart.

Notes: Fixed an issue on macOS where calling
autoUpdater.quitAndInstall()could fail ifcheckForUpdates()was called again after an update was already downloaded.
