Health & Readiness
Rocky impl:
GET /healthz, /readyz✓
Two lightweight probes for load balancers + Kubernetes + the deploy script's smoke step.
GET /healthz — liveness
Returns the literal string ok with 200 OK. No external deps; succeeds even if Postgres / NATS are down.
curl -i https://demo.rocky.exchange/healthz
GET /readyz — readiness
Returns ok with 200 OK when the gateway is ready to serve traffic. Currently a no-op (returns ok unconditionally); a future release wires it to ReadinessProbe.
curl -i https://demo.rocky.exchange/readyz
Both endpoints are unauthenticated and uncached.
