release: v1.23.1 — the menu-bar countdown pauses when the icon is hidden

Fixed

• A timed Keep Awake kept a 1 Hz redraw running while the icon was hidden. The menu-bar countdown
  measured and relaid out its slot every second even with the status item behind the notch, in menu-bar
  overflow, on another Space, or with the display asleep — the one case the app's pause-when-hidden
  rule exists to cover, and an 8-hour window held it for eight hours. The countdown now reads the same
  occlusion verdict the animation does and stops with it, redrawing on the way back so the slot never
  shows the second it went dark on. A countdown in an open menu is unaffected: the menu is its own
  window, visible whatever the status item is doing.
