Desktop Notifications (OSC 9/777)
OSC 9 (iTerm2) and OSC 777 (rxvt-unicode) trigger desktop notifications from terminal applications. These allow long-running commands to notify the user when complete, even if the terminal window is not focused.
How this is tested: Send OSC 9 notification sequence, verify terminal accepts it without error.
