### Added
- Configurable max jobs queue limit with `max_jobs()` builder method
- Backpressure with exponential backoff (1ms → 50ms ceiling) when queue is full
- Thread-safe job count tracking with `AtomicUsize`
- Builder pattern API: `ThreadPool::new(5).max_jobs(100_000)`
- Default max_jobs limit of 50,000 to prevent unbounded memory growth
