Logs live at swarm level now (VictoriaLogs, read through Grafana
Explore). The hive dashboard's own journal viewer goes, with
everything that existed only to serve it:
- frontend: /logs.html, logs.js, logs.css, the H0M3 "Logs" tile and
the per-agent menu's "journal logs ->" link. The build-log list
rules BU1LDS used from logs.css move into builds.css.
- hive-c0re: GET /api/journal/{name} and GET /api/journal-host, and
priv_client::read_container_journal.
- hive-priv / hive-priv-sock: the ReadContainerJournal request, its
JournalQuery/JournalOutput wire types and the journalctl -M executor.
- nix: hive-c0re's systemd-journal supplementary group, whose only
reader was the journal-host handler.
- docs: the L0GS section, the API entry and the security table row.
