BetterDisplay open/close notifications for 3rd party integrations #5174
Description
Simply add notifications for when BetterDisplay is opening/closing so that 3rd party app integrations can use these to apply configuration and react accordingly.
The app will send a notifications on startup:
on startup: pro.betterdisplay.BetterDisplay.launched
on (orderly) quit: pro.betterdisplay.BetterDisplay.terminated
No notification will be sent on a crash.
The contents of the notifications are irrelevant and not-defined.
Launch notification is only sent if integration is enabled (this is the default). The launch notification is sent only after completing the app completes initial self- and device configuration and the app is ready for normal operation.
(note: there is no com.betterdisplay... equivalent for this notification as I might eventually phase those out sometime in the far future and use only the bundle identifier prefix - see #5136).
