Attention Required: notification rules with effects for Omarchy

Rules watch every notification for words and apps and answer with an
effect: nudge, flash, banner, airplane, confetti, blink, sound, focus,
or a command. Silenced notifications that match a rule are let through.
Settings popup behind a bar bell, rules kept in one JSON file.
