ci/woodpecker/pr/ci Pipeline was successful
fix(git-tools): pr-merge queue guard reads CI status from the BASE repo (fork PRs, B1)
For a fork PR, pr-metadata's headRepository names the fork (e.g.
stack-mos-dt-0/stack), and pr-merge passed it to ci-queue-wait via -R.
Woodpecker posts commit statuses on the BASE repository, so the guard read
statuses:null from the fork and every fork merge aborted with
state=malformed rc=3 (#1215, gate-merge-01 B1; standalone queue-wait
against the base repo returns terminal-success on the same sha). Same
family as d339e8fd.

- pr-metadata.sh: normalize baseRepository from Gitea base.repo.full_name
- pr-merge.sh: pass the BASE repo to the queue guard; head repo remains
  for head-sha identity; origin-repo fallback when metadata carries no
  base repository (correct for same-repo PRs)
- test-pr-merge-fork-ci-status.sh: fork-PR regression, CI-reachable via
  test:framework-shell beside its siblings; asserts the guard NEVER sees
  the fork and gets the base repo, head branch and exact sha
- test-pr-merge-queue-branch.sh: its old -R assertion pinned the fork
  repo, i.e. the bug; now asserts the base repo
