Subject: [PATCH] Persist .next/cache across deploys for faster rebuilds

Each deploy creates a fresh worktree and deletes .next, losing the
Turbopack build cache. Now restore .next/cache from the live site
into the stage before pnpm build, so Next.js can do incremental
compilation. After cutover the cache persists in the live .next/ for
the next deploy.
