v2.3.26

Changed

• Push cadence is now hub-decided and tunable (instead of a fixed local INTERVAL).
  The hub returns the interval in each ingest ack and agents obey it on their next push.
  New defaults: hosts every 5s ("realtime" — previously effectively ~60s, which made
  the raw tier duplicate the 1-minute rollup), Kubernetes clusters every 15s (apiserver
  scrapes are heavier). Tune both under Settings → Data & retention → Sampling cadence
  (admin) — no agent redeploy needed. Backed by GET/POST /api/admin/ingest-intervals.

Fixed

• Data & retention now lists the Kubernetes tiers. The backend already tracked
  kube_namespace_stats / kube_deployment_stats / kube_container_stats (size + retention),
  but the page grouped tiers by name with no Kubernetes group, so they were filtered out of
  the display. Added a "Kubernetes" group.
