Fixes 1 bug. Worker API enhancements, worker options now fully wired.

#### To install bunqueue v2.6.81

```bash title="bun"
bun add bunqueue@2.6.81
```

```bash title="npm"
npm install bunqueue@2.6.81
```

#### To upgrade bunqueue

## Removed

- Cleaned up 7 unimplemented WorkerOptions stubs that were type-only (now all options are wired to actual behavior)

## Worker API enhancements

(BullMQ v5 compatibility):
- `concurrency` getter/setter, change concurrency at runtime without restarting the worker
- `closing` property, Promise that resolves when `close()` finishes
- `off()` typed overloads, remove event listeners with full TypeScript support
- `name` and `opts` are now public readonly properties

## Worker options now fully wired

- `skipLockRenewal`, disables heartbeat timer when `true`
- `skipStalledCheck`, disables stalled event subscription when `true`
- `drainDelay`, configurable delay between polls when queue is drained (default: 50ms, was hardcoded)
- `lockDuration`, stored in opts with default 30000ms
- `maxStalledCount`, stored in opts with default 1
- `removeOnComplete` / `removeOnFail`, worker-level defaults applied to all processed jobs

## Bugfixes

- `drainDelay` default corrected from 5000ms to 50ms in documentation
