Splits the single /health endpoint into distinct Kubernetes probe targets: - GET /health/live (+ /health/livez alias): pure liveness probe that returns 200/ok regardless of external dependency state, preventing a transient DB outage from triggering a pod restart loop. - GET /health (readiness): now checks database connectivity, heap memory usage (512 MiB threshold), and event loop lag (100 ms threshold) so Kubernetes can remove an unhealthy pod from rotation without restarting it. Adds MemoryHealthIndicator to encapsulate heap and event loop lag checks, wires it into HealthModule, and updates the k8s/20-api.yaml liveness probe path from /health/livez to the canonical /health/live.

There was a problem hiding this comment.
Clean split between liveness and readiness, and the MemoryHealthIndicator thresholds plus the k8s manifest update make this deploy-ready. Approving and merging.
