fix(ai-term): drop the Agent: echo after an agent swap

The message duplicated the modeline directly above it: the buffer name and the eat state icons already announce which agent is focused, so the echo just lingered as clutter. The no-other-agents echo stays, since it reports something the modeline can't.
