v1.0.0

• Atomic claim via FOR UPDATE SKIP LOCKED (MySQL 8+, MariaDB 10.6+, PostgreSQL 9.5+); on SQLite the single-writer model provides the same guarantee.
• Visibility timeout — jobs whose worker died (crashed, OOM-killed, timed out) are automatically returned to the queue.
• Exponential backoff — retries are rescheduled with baseDelay * 2^retry_count, capped at 1 hour.
• No long transactions — handle() runs outside any transaction, so external side-effects cannot be rolled back.
• Typed jobs via JobInterface + PSR-11 dependency injection through createFromContainer.
• UTC timestamps — all DB times written in UTC regardless of the PHP default timezone.
• PSR-3 logging with full-fidelity error context — Throwables are forwarded under the PSR-3 exception key (trace + previous chain preserved for structured log sinks).
• Observability hooks via JobQueueListener — onClaimed / onCompleted / onFailed / onReclaimed events for metrics, tracing, or context enrichment.
• Long-running worker with signal-driven graceful shutdown and max-jobs / max-runtime / max-memory limits.
• Operational API — reclaimStuck() (callable from a separate cron), getFailedJobs(), retry().
• Optional deleteOnSuccess and LockGuard for preventing overlapping workers.
