Type Alias: JobRetention

> JobRetention = boolean | number | { age?: DurationInput; count?: number; }

Redis retention for finished jobs (BullMQ driver): true removes it as soon as it finishes, false keeps it forever, a number keeps that many most-recent, and { age, count } keeps by age and/or count. Defaults: completed { count: 1000 }, failed false (keep all). The sync driver ignores it (it stores nothing).
