PR #37 removed vite/client from tsconfig types which broke React.Component
typing since vite/client provided React type definitions. Adding explicit
@types/react and @types/react-dom devDependencies is the correct fix as the
plugin doesn't directly depend on vite.
Fixes: TypeScript check failing on main (5 errors in PolarisErrorBoundary)
