Productionizing Workers in Temporal

What this post added

This post details the operational aspects of running Temporal Workers in production, focusing on four key areas: Operational Metrics (monitoring and alerting for activity and workflow task health, scaling based on latency), Incident Response & Tooling (using metrics, logs, and execution history for debugging, and workflow replay), Upgrading and Versioning (using the `getVersion` API for deterministic workflow code changes and task queues for cutovers), and Testing Failure Paths (testing for backlogs by simulating worker outages, capacity planning, and explicitly testing timeouts and retry policies).
