Patched version misses playgrounds

When either Next.js playground runs, its direct workspace dependency still resolves Next.js 16.2.7 because 16.2.11 was added only to the root importer, leaving both applications on the vulnerable release. How this was verified: Both playground manifests and their separate pnpm importers remain pinned to 16.2.7.

Confidence Score: 3/5

This PR is not safe to merge because it leaves both Next.js playgrounds on the vulnerable version it intends to replace.

The root importer gains Next.js 16.2.11, but the independently resolved nextjs and v3 playground importers remain pinned to 16.2.7, so the security fix does not affect the applications using Next.js.

Files Needing Attention: package.json, playgrounds/nextjs/package.json, playgrounds/v3/package.json, pnpm-lock.yaml

Security Review

The upgrade does not reach either workspace package that currently declares Next.js 16.2.7, so the vulnerable release remains active in both playground applications. How this was verified: The playground manifests and their separate pnpm lockfile importers remain pinned to 16.2.7 while 16.2.11 is added only to the root importer.
