New workflow .github/workflows/triage-user-issues.yml. On issues:opened, if
the author is external (author_association not OWNER/MEMBER/COLLABORATOR),
apply user-submitted + priority:P2 + board:backlog using PROJECT_PAT so the
existing sync-labels-to-board.yml fires and sets Status=Backlog /
Priority=Medium on board #2. Maintainer-opened issues are untouched. type:
is left for manual triage.
workflow_dispatch entrypoint added for manual re-triage and the post-merge
live test: both triggers require the workflow to be on the default branch
first (issues:-triggered workflows only run from default; a new
workflow_dispatch is only dispatchable once on default), so validation
happens after the merge to dev.
