Jo 90046cee4f Check and sync frozen comments during auto-update (#1896) ...

## Summary

`auto-update` now validates existing `# frozen:` comments against the
commit pinned in `rev`.

If the frozen comment is stale:
- in normal update mode, `auto-update` updates it to a matching ref when
possible, or removes it if no ref points to the pinned commit
- in `--dry-run`, it only reports the mismatch and does not modify the
config file
- in `--check`, it behaves like `--dry-run` and exits with status 1 if
updates would be made

This keeps frozen comments consistent with pinned SHA revisions without
adding a separate command.

## Example
```console
❯ cargo run -- auto-update --check
