✨ Revise observability features by introducing new health and liveness endpoints (/livez and /readyz), updating Prometheus metrics to track NATS consumer pending messages, and enhancing telemetry integration for better monitoring. Update documentation to reflect these changes and ensure consistency in metric naming conventions.
