Make Super+comma dismiss, invoke, or focus the newest notification by its buttons
Count a notification's click as one of its actions on Super+comma
Count a notification's click as one of its actions on Super+comma (#16701)

dhh proposed and merged omacom/omarchy#16699 and its follow-up omacom/omarchy#16701 into quattro. Super+comma now invokes a notification's sole action or opens keyboard selection when several choices exist. Plain dismissal moves to Super+Alt+comma.

The follow-up accounts for clickable notifications without buttons, such as WhatsApp web notifications. The resulting commit also counts a native sender's own window as an available action, covering apps such as Signal. These are development-branch changes.
