Subject: [PATCH] ci: drop --depth=1 base fetch in migration-policy (shallow
 graft caused false positives)

The base ref was fetched --depth=1 while policy.yml checks out full history; the shallow graft made origin/BASE..HEAD reappear historical base commits after an Update-branch merge, tripping the commit-metadata rule. Fetch the base full-depth (matching the already-fixed variant in rustnzb).
