"""Activation-wiring tests (integration branch): prove the WS seams that the
``serve`` path flips ON are actually wired, without a live Slack socket.

Covers:
* run-team ``_build_context_provider`` returns the handbook loader (WS5 / D10).
* run-team ``_build_coordinator`` threads that context_provider into the planner
  node factory.
* run-team ``_build_coordinator`` sets a ``/new-task`` callback that starts a
  task on the SAME coordinator with transport_name="slack" (WS2).
* ``default_slack_listener_factory`` forwards ``new_task_callback`` to the
  SlackListener (WS2).
* ``Coordinator`` stores ``new_task_callback`` / ``set_new_task_callback`` and
  forwards it when it builds the default listener.
