+Drop the unused `team` value from `sys_business_unit.kind` (ADR-0057 addendum D11).
+
+The `team` kind collided head-on with the first-class `sys_team` object: a
+`kind='team'` business unit walks the hierarchical `BusinessUnitGraphService`,
+while `sys_team` is the flat better-auth collaboration grouping served by
+`TeamGraphService`. `kind` is a display-only categorisation hint (it does not
+change graph semantics) and had **zero** usages anywhere in the repo, so this is a
+safe narrowing with no data migration. New enum:
+`company | division | department | office | cost_center`.
