## Simple Mode: 8 advanced features

All built on top of existing Queue/Worker APIs with zero core modifications:
- **Batch Processing**: accumulate N jobs, flush on size or timeout, per-job Promise resolution
- **Advanced Retry**: 5 strategies (fixed, exponential, jitter, fibonacci, custom), `retryIf` predicate
- **Graceful Cancellation**: AbortController per job, `cancel()`, `isCancelled()`, `getSignal()`
- **Circuit Breaker**: auto-pause worker after N consecutive failures, half-open recovery
- **Event Triggers**: declarative "on job A complete → create job B" with optional conditions
- **Job TTL**: expire unprocessed jobs, per-name overrides, runtime updates
- **Priority Aging**: automatically boost priority of old waiting/prioritized jobs

## Modular architecture

Each feature in its own file under `src/client/bunqueue/` (max 300 lines each)

## 50 unit tests

For Simple Mode features, 29 integration assertions

## Comprehensive documentation

Super detailed guide with architecture diagrams, code examples, and interaction notes
