chore(guide): satisfy React type peer dependency [Codex]

[jderochervlk]

The guide workspace emitted a peer-dependency warning because packages in its dependency tree request @types/react, while the workspace did not provide it.

This adds the already-locked React type package as a development dependency, matching the docs workspace and satisfying the guide's peer requirements without changing the production dependency graph.
