## 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).
