f674419e75* Fix `put_status`/`put_error` behavior - use `put_error` instead of `put_status` for command errors - prevent status message output to console during initialization - use `put_error` for side effects in command errors - add `&` prefix in status messages to force screen flush - flush screen in `qe_display()`, remove redundant calls to `dpy_flush` - fix gcc compilation errors and warnings - remove most references to `global_screen` - free font cache before closing the screen - prevent mouse handling upon focus detection * drop CI on macos-12
