"""Feature 1: pipeline starts on status -> In Progress, not on creation.

  * work_item.created / issue created -> NO task, NO branch, NO analyst.
  * issue updated -> In Progress (from backlog) -> task created + analyst enqueued.
  * a second In Progress update while the agent is busy -> NO duplicate, NO
    restart (busy-guard).
  * In Progress returned from Needs Input (agent idle) -> agent RELAUNCHED.
