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>

## Ejemplo
|
|
|
|
```go
|
|
id, err := JobEnqueue(q, "send_email", `{"to":"user@example.com"}`,
|
|
WithPriority(5),
|
|
WithMaxAttempts(5),
|
|
)
|
|
```
|
|
|
|
## Notas
|
|
|
|
Usa `github.com/google/uuid` para generar el ID. El payload por defecto es "{}". El campo `scheduled_at` por defecto es `time.Now().UTC()`. La prioridad mas alta se procesa primero (ORDER BY priority DESC).
