Bounds Docker time-series growth (the main scaling concern). New docker_metrics_hourly table + docker_006 migration; a plugin retention module (docker.run_retention capability) rolls raw docker_metrics older than the raw window into hourly averages (idempotent upsert), deletes the rolled raw rows, then prunes stale rollups + lifecycle events. Core cleanup.py drives it each hourly run via the capability (no plugin-model import), reading the three retention windows fresh from settings so changes apply without restart (rule 25). Settings → "Thresholds & Retention" gains a Docker retention card (raw / rolled-up / events windows, working defaults 7/90/30 days). Unit tests cover the hour-aligned cutoff/bucketing helpers; integration test exercises the real rollup-average + prune across both windows. Milestone 77 task #941.
