"""MoA display events honour the ``-Q`` quiet contract.

``-Q`` (machine-readable CLI output) nulls ``agent.tool_progress_callback`` and sets
``tool_progress_mode = "off"``; the MoA reference relay reads the callback at emit time, so
quiet sessions must emit nothing and interactive sessions must relay every event.
