Add dimos-robot end-to-end test with agents

[paul-nechifor]

This test checks that dimos-robot works end to end.

• It starts dimos-robot run demo-skills.
• It checks that the sample sum_numbers skill is registered.
• It sends two numbers to add through /human_input.
• Checks that the agent gives back the right answer.
• Checks that the sum_numbers skill was used.

	def stop(self) -> bool:
	"""Stop the robot's movement.
	Returns:
	bool: True if stop command was sent successfully
	"""
	# Cancel timer since we're explicitly stopping
	if self.stop_timer:
	self.stop_timer.cancel()
	self.stop_timer = None
	return True

stop() override drops movement halt and disconnect logic

The class defines stop() twice. The later definition replaces the earlier one that sent a zero TwistStamped, shut down the WebRTC connection, and stopped the event loop. As a result the timer created in move() now calls the lightweight version that only cancels the timer and returns True, so auto‑stop never actually stops the robot or tears down the connection. This leaves the robot continuing its last motion and leaks the connection thread.

	def wait_exit() -> None:
	while True:
	try:
	time.sleep(1)
	except KeyboardInterrupt:
	print("exiting...")

wait_exit ignores KeyboardInterrupt and never returns

wait_exit() swallows KeyboardInterrupt in an endless loop without breaking or re‑raising. Any process that calls wait_exit() (e.g., unitree/run.py) can no longer be interrupted with Ctrl+C and must be killed externally. The handler should exit the loop or propagate the interrupt so the program can terminate cleanly.
