Add delivery modes to mail messages: - queue (default): message stored for periodic checking - interrupt: inject system-reminder directly into session New features: - --interrupt flag on gt mail send for urgent/lifecycle messages - --quiet flag on gt mail check for silent non-blocking checks - gt mail wait command to block until mail arrives (with optional timeout) Interrupt delivery injects a system-reminder via tmux send-keys, useful for stuck detection, nudges, and urgent notifications. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
