32-32: LGTM. Properly resolves the implicit dependency issue.

The language-data package is usually installed as a dependency of langcodes, making it a valid implicit transitive dependency that this PR now makes explicit. The placement is correct (alphabetically between langcodes and litellm), and the lack of version pinning is consistent with other unpinned dependencies in the file and is appropriate given that the latest version (1.4.0) was released Nov 28, 2025. This change directly addresses the CI failures noted in the PR objective.
