Problem
On macOS after a long sleep, Feather may hang with a spinning cursor when clicked from the tray and never show a window. Force quit + relaunch is required.
Repro
Fix
Subscribe to native macOS sleep/wake notifications (NSWorkspaceWillSleep/DidWake) via a small Objective-C++ observer and trigger UI recovery on wake. This avoids heuristics and ensures recovery runs only on actual wake events.
