Reverts passepartoutvpn/passepartout-apple#318
`Codable` compliance at the domain layer (`Profile` etc.) makes this
change in serialization destructive.
It's crucial that the data layer has full control over how entities are
(de)serialized.
Do not leave this choice up to the domain layer by defining an enum as a
raw value type, because any change in the enum raw value would literally
be a disaster, i.e. _any_ serialized data would break instantly.
* Make specific message levels a default extension
* Define Loggable protocol
* Keep track of message originator metadata
* Fix tracing of Core Data logs
* Log query on entity not found
Use bundle as a means to provide Mac APIs to Catalyst app.
In order to cross the @objc wall set by the Mac Bundle mechanism,
Swift structures cannot be used directly and must be bridged
through ObjC facades.
Create NSMenu in MVVM style and install it on app launch. Make
sure to do it in AppDelegate.applicationDidFinishLaunching(),
because doing it as early as in PassepartoutApp.init() would
crash Mac code.
Use .representedObject to own view models.
With menu in place, app can be sent to background when main window
is closed. Requires multiple documents support for app not to die
instantly.
