Research direction

The issue concerns the Install @types code fix added by PR #19130 and its handling of package.json, package-lock.json, and yarn.lock. Start by reading that change and tracing why npm is always selected. Done means the code fix supports Yarn projects and updates yarn.lock correctly; verify the behavior with the relevant code-fix tests if available.
