fix(window): show the window buttons in full screen on macOS (#2015)

Native full screen moves a window's buttons into the bar revealed with the menu bar, and a project tab shown in its group's full-screen Space has none, so the title bar's slot for them stayed empty. The title bar now draws them there while the window fills the screen: close closes that project's tab, the green button leaves full screen, and minimize is disabled.
