fix(unitree): marshal stop_movement zero-twist onto the loop thread

[ruthwikdasyam]

Problem

stop_movement called _publish_movement(0,0,0) directly from non-loop threads

Solution

Marshal the send onto the connection's event loop via asyncio.run_coroutine_threadsafe, matching the existing pattern in publish_request and move().

How to Test

dimos run teleop-hosted-go2-multicam

Greptile Summary

This PR moves the Unitree stop command onto the connection event loop.

• Wraps the zero-twist publish in a coroutine.
• Schedules it with run_coroutine_threadsafe.
• Logs failures while dispatching the stop command.

Confidence Score: 5/5

The event-loop-thread stop path can delay the zero-twist command.

• External-thread callers now use the connection event loop.
• A call made from that same loop waits for work that cannot run until the wait ends.
