WorkloadDeployment now implements the /scale subresource (wasmCloud/wasmCloud#5244), so kubectl scale, HPA, and KEDA work natively. Add a how-to covering the conceptual model, External-metric HPA, KEDA ScaledObject with OTel-driven scaling, the operator-managed selector label, and limits. Cross-link from the CRDs reference, operator overview, and k8s landing page. Add KEDA and HorizontalPodAutoscaler entities to the JSON-LD dictionary. Signed-off-by: Eric Gregory <eric@cosmonic.com>

| ## Kubernetes Event-Driven Autoscaling (KEDA) | ||
|
|
||
| [KEDA](https://keda.sh/) is a CNCF Graduated project that serves as an event-driven autoscaler. KEDA's `ScaledObject` wraps the same `/scale` subresource and adds a large catalog of [scalers](https://keda.sh/docs/latest/scalers/) (Prometheus, Kafka, NATS, OTel, cloud queue services, and so on). Behind the scenes, KEDA creates and manages an HPA on your behalf. |

There was a problem hiding this comment.
This is the important call out (just making not really), that KEDA creates the HPA for you; you don't create the HPA artifact yourself if using KEDA. Also it is ScaledObject I couldn't remember earlier today lol.
