scripts/issue-qualification-audit.sh: lists OPEN issues missing a `priority:` label
(the #237 ranking keys off priority:/gate labels, so an unlabeled issue is invisible
to it). "Fully qualified" = has a priority: label; gate-vs-backlog derives from the
review label / milestone, and a milestone is NOT required (backlog is unmilestoned).
Advisory (exit 1 if any unqualified); fail-open without Gitea creds. Wired into the
kickoff session-end protocol + a lore bullet. Tested live (flagged 2) + no-creds no-op.
