allow the use of custom shell command actions in wlr/taskbar #4720
Description
wlr/taskbar only allows "actions" in on-* config entries. i'd like to execute a shell command, or at least get to run a shell script before and after the action (synchronously). i need this so i can disable hyprland cursor warps before activating the new window and for enabling them again after. another way could be passing some sort of window-identifying property to a new on-click-cmd config property as an argument.
this is my very ugly and incorrect implementation which adds the before-action and after-action options for demonstration:
