PR-status source candidates were every configured remote, so a checkout
carrying contributor forks matched a fork's closed PR whose head merely
shared the branch name — a fork's 'main' surfaced on the local main in the
git and work-status panels. Only the ranked-first remote (the one the
branch pushes to) and its fork network are PR sources now; other remotes
remain search targets but their owner:branch heads no longer count.
