Npm warning on new-mini-app-quickstart

```bash
new-mini-app-quickstart git:(main) npm install
npm warn ERESOLVE overriding peer dependency

```

I know these are just warning but I can resolve and contribute?

Start by running npm install in new-mini-app-quickstart and inspect the dependency declarations responsible for react, valtio, and use-sync-external-store. Trace the peer-dependency and deprecated-package warnings, then verify that installation completes without the reported warnings.
