FN-7045: capitalize Code Review step name

Normalize the built-in Code Review workflow label and cover the display-name invariant.

- Rename the compound-engineering built-in code-review node to "Code Review".
- Add regression coverage that rejects lowercase built-in Code review node names.
- Add a patch changeset for the published CLI package.
