| job_cleanup | function | go | infra | 1.0.0 | impure | func JobCleanup(q *JobQueue, olderThan time.Duration) (int64, error) | Elimina jobs en estados terminales (completed, failed, dead) cuyo created_at sea mas antiguo que olderThan. Retorna el numero de filas eliminadas. Util para mantener la tabla compacta en apps de larga duracion. |

Ejemplo
// Limpiar jobs terminados hace mas de 7 dias
n, err := JobCleanup(q, 7*24*time.Hour)
fmt.Printf("eliminados: %d jobs\n", n)
Notas
Solo elimina jobs en estados terminales: completed, failed, dead. Los jobs pending y running nunca se eliminan. El cutoff se calcula en UTC. Llamar periodicamente con CronTicker u otro scheduler para mantener la tabla compacta.
