Owner decision 2026-09-26: "delete if there's no history,
retire/deactivate if there is". A definition with no completion event
on any instance is hard-deleted (instances, assignees, windows, the row
and its unreferenced rule) in one transaction under the connection
lock; one with history is retired via set_quest_definition_active and
everything is preserved (D-005).
- core: QuestDefinitionsDao.delete_if_no_history (atomic history check +
deletes) and quest_definitions.delete_quest_definition
- api: DELETE /api/v1/admin/quest-definitions/{id} on the admin router
- admin: Delete task control with a hybrid-explaining confirm in the
edit sheet; the list removes or shows the row inactive
- docs: ADMIN-SPEC Definitions section
