Subject: [PATCH] fix(build): disable webpack build workers to reduce memory
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Next.js spawns per-worker webpack processes — each has its own heap.
On low-RAM servers total usage exceeds available memory → SIGKILL (silent).
webpackBuildWorker: false runs compilation in main process only.
Also lower JS heap cap to 512MB to leave room for OS + pnpm.
