Delete a team. Its memberships are deleted with it. For companies with nested teams, a team that still has sub-teams cannot be deleted: the request fails and lists them. This version does not expose an endpoint to re-parent a team, so those sub-teams have to be deleted first, working from the deepest level up; from 2026-10-01 a move endpoint is available to re-parent them in one call instead. Deletion never cascades — sub-teams are never deleted along with their parent.
