openhands 539e6d3fad fix(docker): harden image and automate safe VPS updates
- Use floating node:alpine that tracks the latest supported LTS; pnpm
  bootstrap follows package.json's packageManager pin.
- Drop corepack (removed from node:26), install pnpm via npm global.
- Add pnpm fetch + offline install for stable dependency-layer caching.
- Run as non-root nextjs (UID/GID 33 = host www-data) with tini as PID 1
  for correct signal handling.
- Open node engines to >=20.9.0 so patches/minors float automatically.
- Add docker-preflight.sh (per-VPS checks incl. --fix) and gate docker-update.sh
  so Node major upgrades require explicit review while patches deploy silently.

# docker-update.sh — Automatic daily update for the Dockerized EpicNext-CMS.
#
# Steps:
# 1. Verify the working tree is clean (uncommitted changes abort).
# 2. git pull (fast-forward only).
# 3. Run CMS migrations on the HOST (the slim runtime container has no source).
# 4. docker compose build (auto-detects pnpm/yarn/npm via lockfile).
# 5. docker compose up -d && wait for a healthy container.
# 6. Record everything in update.log.
#
# Exit codes: 0 ok, 1 update skipped, 2 build/deploy failed, 3 health failed.
