/**
 * `chant dev pinned-upgrade <lexicon-dir>` command implementation.
 *
 * Detects whether a pinned-version lexicon (k8s, gcp, docker, gitlab) has a
 * newer stable upstream release. When it does, it dry-run bumps the pinned
 * version constant, regenerates + surface-diffs (via #524's regenLexicon), then
 * reverts the bump — leaving the working tree unchanged.
 *
 * This command only REPORTS. Branch/PR automation lives in #527.
