Deployment fails during application creation when using template because assets have not been built

### What versions & operating system are you using?

Node v22.12.0, Ubuntu 24.04.2, Wrangler 4.19.2

### Please provide a link to a minimal reproduction

_No response_

### Describe the Bug

When running `npm create cloudflare` using one of the templates which require a build step, in this case `vite-react-template`, it asks you if you want to deploy your application and if you select `yes` it runs `npm run deploy` but this fails because we have not run `npm run build` so the assets aren't actually there.

I would expect it to automatically run the build script before the deploy script.

### Please provide any relevant error logs

```
ewan@ewan:/media/ewan/ssd/projects$ npm create cloudflare@latest -- --template=cloudflare/templates/vite-react-template

> npx
> create-cloudflare --template=cloudflare/templates/vite-react-template

```

Start with the vite-react-template application-creation flow and its npm run deploy and npm run build scripts, then inspect how the create-cloudflare deploy prompt invokes them. Reproduce the issue with the template and verify that choosing deployment after creation builds the assets so the assets.directory path exists and deployment succeeds.
