Conflicts with experimental's pause_toggle, steam_menu and command: actions and its AnnounceOverlay: both kept. The spin bindings join the Meta tap in the defaults, spinning doesn't need pointer mode, and like other actions it does nothing while Frametop is paused. AnnounceOverlay now sends through the PR's SendPointer. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
