PyObjC UserNotifications Framework

PyObjC is a bridge between Python and Objective-C, allowing full-featured macOS applications and scripts to be written in Python. The `pyobjc-framework-usernotifications` package provides Python wrappers for the macOS UserNotifications framework, enabling developers to send and manage user notifications on macOS. The current version is 12.1, and PyObjC generally follows a release cadence tied to macOS SDK updates and Python version support.
