rsyslog was duplicating journald's logs into /var/log files on the built image, which serves no purpose since journald already retains everything. Purge rsyslog and bound journald to 10G total (with automatic rotation) via a journald.conf.d drop-in. Also enable node_exporter's systemd collector, scoped to the vector-store service and systemd-coredump units, so unit state is visible in metrics.
