wtf is reaction-health-check?

This package adds a simple health-check endpoint to a Reaction Commerce server. When you visit the /health route on your server, it tells you whether the server is running and healthy, useful for monitoring tools, load balancers, or deployment systems that need to know if your service is up and working. Think of it like a heartbeat monitor. Instead of waiting for actual customer requests to fail and finding out something's wrong, you can ping this endpoint regularly to catch problems early. Tools like Kubernetes, Docker health checks, or monitoring services can automatically check this route every few seconds and take action (like restarting the server or alerting your team) if it stops responding. The package integrates directly into Reaction Commerce, the open-source e-commerce platform, so if you're running a Reaction store, you can drop this in and immediately get this monitoring capability. It's particularly useful if you're running your server in a cloud environment or using orchestration tools that expect services to expose a health endpoint. The implementation is lightweight, it just creates one route and likely returns a simple "OK" status to confirm the server is alive. No configuration or complex setup needed.
