Subject: [PATCH] Add smart activity monitoring to silence noisy programs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Automatically disable activity monitoring for constantly-updating programs:
- lazygit: Git TUI with frequent display updates
- btop: System monitor with continuous refreshing
- htop: Process monitor
- watch: Repetitive command execution
- tail: Log file following

Features:
- Auto-detection via tmux hooks (after-new-window, window-pane-changed, pane-exited)
- Re-enables monitoring when switching to normal programs
- Manual toggle with Ctrl+a A
- Eliminates false activity notifications while preserving useful ones
