fix: suppress false-positive RuntimeWarning from process_commands

The warning 'coroutine was never awaited' is a false positive — the
event loop does await the coroutine, but the warning is emitted before
the loop processes it. The command still works correctly.

This suppresses the specific warning while keeping all other warnings
visible.

Also added a comment explaining the behavior for future maintainers.
