Implementa el subsistema completo de background jobs para apps Go en el dominio infra. 9 funciones + 3 tipos + 17 tests, todos pasando. - Tipos: Job (product), JobQueue (product), JobStatus (sum) con JobHandler, EnqueueOption y WorkerOption usando functional options pattern - job_queue_create: CREATE TABLE + indices + WAL mode - job_enqueue: INSERT con UUID (github.com/google/uuid), WithPriority/WithScheduledAt/WithMaxAttempts - job_dequeue: SELECT+UPDATE atomico en transaccion exclusiva, filtro por jobTypes - job_complete / job_fail: transiciones de estado; fail → dead cuando attempts >= max_attempts - job_status_summary: pura, formatea conteo de jobs por estado - job_worker: poll loop bloqueante, context-cancelable, graceful shutdown - job_worker_pool: N workers con golang.org/x/sync/errgroup - job_cleanup: DELETE jobs terminales mas viejos que olderThan Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

| job_fail | function | go | infra | 1.0.0 | impure | func JobFail(q *JobQueue, jobID string, errMsg string) error | Incrementa el contador de intentos y transiciona el job a 'failed' (reintentable) o 'dead' (sin mas intentos) segun si attempts >= max_attempts. Almacena el mensaje de error. |

Ejemplo
if err := handler(job); err != nil {
_ = JobFail(q, job.ID, err.Error())
}
Notas
El UPDATE es atomico: incrementa attempts y decide el nuevo status en un solo SQL con CASE WHEN. Si (attempts + 1) >= max_attempts → status='dead', sino → status='failed'. Los jobs failed pueden ser reintentados manualmente reseteando su status a 'pending'. Los jobs dead no se procesan automaticamente.
