fix: clean up broken symlinks after .pnpm removal, keep root next/

After deleting .pnpm/, symlinks in apps/web/node_modules/ become
dangling and break cp -r. Remove broken symlinks before copying.
Since apps/web/node_modules/next is now gone, server.js resolves
from root node_modules/next — so don't delete that copy.
