Steve Yegge 04dd267492 feat: gt mail send now sends tmux notification to recipients
- Add DisplayMessage/DisplayMessageDefault to tmux package for non-disruptive
  status line notifications
- Change mail send to always notify recipients (not just high priority)
- Use display-message instead of send-keys to avoid disrupting agent input
- Support notifications for mayor, polecat, and refinery sessions

Closes gt-7lt
