Panel event delivery is unreliable on macOS 26 (clicks pass through even
with the app active and the panel key). The selection flow is now driven
by a CGEventTap that sees and consumes mouse events system-wide: hover
highlights windows, clicks capture them (rounded), drags marquee-select,
Esc cancels. Requires Accessibility permission, prompted on first use;
falls back to panel events when unavailable.
