[AI] Add Yarn constraints to enforce consistent dependency versions (#7229)

* [AI] Add yarn constraints to enforce consistent dependency versions

Adds a `yarn.config.cjs` that uses Yarn 4's built-in constraints feature
to detect when the same dependency is declared with different version
ranges across workspaces. Workspace protocol references and
peerDependencies are excluded from the check.

Also adds a `yarn constraints` convenience script and the `@yarnpkg/types`
dev dependency for type-checked constraint authoring.
