fix: enable Globe+F (fn+F) fullscreen shortcut (#507)

* fix: enable Globe+F (fn+F) fullscreen shortcut for SwiftUI lifecycle app

SwiftUI lifecycle apps don't create a real NSMenuItem for "Enter Full Screen" —
the shortcut shown in the View menu is a visual hint only, with no key
equivalent binding. macOS maps Globe+F to ⌃⌘F, so install a local event
monitor to bridge the gap.

* fix: use KeyCode enum and add CHANGELOG entry
