import-agent-out-beliefs-not-resurrected

Summary

When beliefs are imported from another database with an OUT or STALE status, that status is treated as sticky — the local system preserves it as-is rather than re-evaluating whether the belief should be true based on local evidence. This means the importing system defers to the source's judgment about what has been retracted or gone stale, which prevents contradicted or outdated claims from silently coming back to life just because their supporting reasons happen to exist locally.
