rawmode_linux.go only cleared ICANON|ECHO but left ISIG enabled, so the terminal driver caught Ctrl+C and generated SIGINT. signal.Notify caught the SIGINT but no goroutine consumed the channel, effectively swallowing the signal. Fix: also clear ISIG so Ctrl+C is delivered as byte 0x03, which the line editor handles with os.Exit(130). Also set VMIN=1, VTIME=0 for proper blocking read behavior.
