Subject: [PATCH] node-service-manager: the kernel-log verb beside journal
 (issue 1975)

The kernel's messages of this boot or an earlier one (boot 0, -1, ...), in a window, narrowed to a
priority and a text, at most 2000 lines, the journal's argument forms; replaces journalctl -k,
journalctl -k -b -1 and dmesg. seatgen -check is clean.

Builds: issue 1975, the operator's request of 2026-11-12 (the lead's handover; no design line names the verb)
