- check-disk-space.sh: always prune dangling images, unused volumes, and
build cache >7 days on every run (not just at critical threshold)
- check-disk-space.sh: auto-remove node_modules if found on server
(never needed — Docker builds inside containers)
- disk-check launchd: reduce interval from 60min to 15min to catch
disk issues faster (yesterday we hit 100% before hourly check caught it)

- alerts.yml: replace broken node-exporter disk alerts with Pushgateway-based ones
- master-overview.json: add "Recent Errors (Loki)" section with live error log
stream, error rate timeseries and top error sources barchart
- move-colima-to-external-ssd.sh: guided script to move 200GB Colima VM
