Subject: [PATCH] fix(react): add resolve.dedupe for react/react-dom to prevent
 CJS multi-instance
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

React 19.2.5 is pure CJS. Rollup's CJS→ESM interop can create separate scoped
ReactSharedInternals objects for react and react-dom, causing hooks to see a null
dispatcher on the server build. resolve.dedupe forces a single shared instance.
