The bin names should reflect the thing they manage. `refresh bar` is
misleading because the command resets the entire shell.json (which holds
plugins beyond just the bar), and `restart quickshell` names the runtime
rather than the product. Both now end in `-shell` to match the rest of
omarchy-shell.
Updates every caller in autostart, the menu, voxtype helpers, and the
shell README. No behavior changes.
