react-doctor fails with pnpm catalog: protocol in package.json

Bug

react-doctor v0.0.30 fails with No React dependency found in package.json when the project uses pnpm's catalog: protocol for dependency versions.

Reproduction

// package.json
{
  "dependencies": {
    "react": "catalog:",
    "react-dom": "catalog:"
  }
}

# pnpm-workspace.yaml
catalog:
  react: 19.2.4
  react-dom: 19.2.4

$ npx react-doctor@0.0.30 .
react-doctor v0.0.30
Something went wrong. Please check the error below for more details.
No React dependency found in package.json

Expected

react-doctor should recognize "catalog:" as a valid version specifier (resolved by pnpm at install time) and either:

1. Parse the actual version from pnpm-workspace.yaml
2. Fall back to the installed version in node_modules/react/package.json

Context

The catalog: protocol is a pnpm workspace feature for centralizing dependency versions. It's been stable since pnpm v9.5. Our CI (GitHub Actions) runs npx -y react-doctor@latest and it has been failing on every branch since ~April 1, 2026.

Environment

• react-doctor: 0.0.30
• pnpm: 10.x
• Node: 24.x
• React: 19.2.4 (via catalog)
