[VibeDefend] Emergency Switch: Push a Rule to Every Agent in One Minute

A compromised npm package is announced at 10:00. At 10:01, your security team blocks its installation on every agent of every developer in the organization. The emergency switch pushes a guard or rule to all agents at once, and can put the whole organization in restrictive mode during an incident. Supply chain response goes from hours of Slack messages to a single action.
