Bound docker_logs growth in the periodic cleanup task (same architecture as the
metrics/events retention). run_docker_retention gains logs_retention_days +
logs_max_bytes_per_container: it prunes lines past the age window, then keeps
only the newest ~cap bytes per (host, container) via a window-function ring
(exclusive-prefix sum, so the newest line always survives even if it alone
exceeds the cap). Containers rotate independently.
- settings DEFAULTS: docker.logs.enabled/exclude/retention_days(3)/
max_bytes_per_container(5MB) — operator preference: ~3 days / ~5 MB
- cleanup.py reads the two windows fresh each run (rule 25, no restart)
- integration rotate test: age prune + per-container byte cap + isolation
