## `prefixKey`, namespace isolation for `Queue` and `Worker`

New option lets multiple environments, tenants, or services share the same broker without their jobs, workers, cron schedulers, stats, pause state, DLQ, or rate limits overlapping. `Queue.name` still reports the logical name; the prefix is applied internally to the server-side key. Backward compatible, without `prefixKey`, behavior is identical. Resolves the cron `name` PRIMARY KEY collision in [#77](https://github.com/egeominotti/bunqueue/issues/77). Example:
```typescript
const dev = new Queue('emails', { prefixKey: 'dev:' });
const prod = new Queue('emails', { prefixKey: 'prod:' });
// Workers must match the prefix to consume jobs from the producing queue
new Worker('emails', processor, { prefixKey: 'dev:' });
```
