Replace the tray-icon/muda macOS backend with a hand-rolled NSStatusItem +
NSMenu built directly on objc2 0.5 / app-kit 0.2 (the same objc2 generation
winit 0.30 uses), so the menu lives in winit's NSApplication runtime and the
target-action dispatches. tray-icon's bundled muda collided with the muda
Slint's winit backend already registers and never fired the menu items. This
drops the tray-icon dependency and its whole GTK tree from the lockfile.
- Menu-bar icon pinned to 18pt via NSImage::setSize; the 44px PNG was
rendering at native pixel size (giant icon).
- The status button gets its own target-action firing on left AND right
mouse-up: left-click toggles the window, right/control-click pops the menu
transiently (setMenu -> performClick -> clear, the non-deprecated
replacement for popUpStatusItemMenu:). The menu is no longer permanently
attached, so a left-click no longer opens it.
- Add the NSEvent feature to objc2-app-kit.
