I think this treats the symptom rather than the cause.

metadata.json is missing @sitecore-content-sdk/personalize on a Yarn Pages Router app because the package is not installed: nextjs imports it in for exmaple proxy/personalize-proxy.js but only declares it as a peer, the Pages Router template does not list it, and Yarn does not install missing peers. With this PR, yarn build still fails:

Module not found: Can't resolve '@sitecore-content-sdk/personalize'

and metadata.json would list a package that is not in node_modules or the lockfile.

Add @sitecore-content-sdk/personalize to the Pages Router template's dependencies, as the App Router template already does. I tried it on a scaffolded app with Yarn 1.22.22 yarn build passes and metadata.json contains personalize at 2.1.0, so the metadata.ts changes can be dropped.

If the peer lookup stays, it has a few problems: the version comes from the registry rather than the install, every build makes blocking network calls (20s timeout per missing peer), registry auth and proxy config are ignored, and only process.cwd()/node_modules is checked, which misses hoisted and pnpm installs.
