ci: pin Node 20 for backend + install bun for OpenNext frontend build

↗ view on GitHub · Pol Guixe · 2026-06-03 · def45505

Two bootstrap fixes after first deploy attempt:

- backend/package.json: add engines.node ">=20" so Nixpacks installs Node 20
  on Railway instead of the default 18 (which is EOL and was removed).
- .github/workflows/ci-cd.yml: install bun in deploy-frontend before the
  OpenNext build. OpenNext detects frontend/bun.lock and invokes `bun run
  build`, which fails on a runner with only Node installed.
