-- A parent job's child dependencies of a given status, sliced [offset, limit]
-- and joined to the child job rows (for fetchJobs). Params: $1 parent_queue,
-- $2 parent_id, $3 status ('pending' | 'processed'), $4 offset, $5 limit
-- (NULL = no limit). `total` is the full number of matching dependencies
-- (COUNT(*) OVER(), computed before the slice). `dep_value` is the stored
-- result for processed children. The remaining columns are the child
-- `job` row consumed by rowToJobJson.
