v1.11.0 had a critical proxy connection leak in the instance-manager
(longhorn/longhorn#12575) that consumed 38.8GB on apollo, pushing the
server to 92% memory with swap exhausted.
v1.11.1 fixes the leak. Also adds a 2Gi per-container LimitRange in
longhorn-system as a safety net against future regressions.
Add new bases for cert-manager (Let's Encrypt + wildcard cert), Longhorn
distributed storage, and monitoring (kube-prometheus-stack + Loki + Tempo
+ Grafana OIDC). Add cloud-init for Scaleway Elastic Metal provisioning.
Production overlay: add patches for postgres sizing, SeaweedFS volume,
OpenSearch storage, LiveKit service, Pingora host ports, resource limits,
and CNPG daily barman backups. Update cert-manager.yaml with full dnsNames
for all *.sunbeam.pt subdomains.
