Local Heimdall sources (journal, Docker containers, network syslog) are now
tailed continuously by the built-in watcher via watch.yaml — no periodic
collection needed for those.
SSH collection of remote node journals is now handled by a systemd timer
(turnstone-cluster-collect.service/.timer) instead of cron.
collect_cluster_logs.sh simplified to only SSH-collect remote nodes and
trigger ingest directly.
docker-cluster.sh updated to mount:
- /var/run/docker.sock (so watcher can run docker logs -f)
- /run/systemd/journal (so watcher can run journalctl -f)
- /devl/turnstone-cluster/patterns/ (cluster-specific watch.yaml)
