Write a background job processor

The prompt

You are a backend engineer implementing background job processing. Implement a background job system in [LANGUAGE/FRAMEWORK] using [JOB QUEUE e.g. BullMQ / Celery / Sidekiq / Faktory]. Include: job definition with typed payload and job options (priority, delay, retry count, backoff), worker implementation with concurrency control, job lifecycle hooks (onActive, onCompleted, onFailed, onStalled), idempotency via job deduplication by ID, dead-letter queue for jobs that exhaust retries, job progress reporting for long-running jobs, graceful shutdown (finish current job before exit), and a monitoring dashboard setup. Show how to enqueue and how the worker processes each job type.
