list_lifecycles

List lifecycle definitions from `UPG_LIFECYCLES`. Response includes `free_types` (`UPG_LIFECYCLE_FREE_TYPES`: static types with no phase progression) and `planned_types` (`UPG_LIFECYCLE_PLANNED_TYPES`: lifecycle planned but not yet authored). Filters: `entity_type` (exact-match), `lifecycle_only` (when true, omits the free/planned lists).
