macOS only enumerated on-screen windows and dropped minimized AX windows,
so an app whose window was minimized, hidden or on another Space (any
full-screen app) could not be observed, and agents fell back to
--restore-window, which activated every window of the app and switched
the user's Space.
Enumerate every window, keep the off-screen ones accessibility can still
read (other-Space windows by remote token, closed windows dropped by
their Space membership), and report their real minimized and off-screen
state. Background pointer and key input on such a window refuses before
sending anything. --restore-window now raises only the target window,
once per request, and delivery is measured from whether the target
became frontmost.
