Subject: [PATCH] bpo-39580: add check for CLI installation on macOS (GH-20271)

Adds a simple check for whether or not the package is being installed in the GUI or using installer on the command line. This addresses an issue where CLI-based software management tools (such as Munki) unexpectedly open Finder windows into a GUI session during installation runs.
