- scripts/setup-project.sh: one-command VPS setup (user, dir, deploy, sudoers, systemd, nginx)
- scripts/deploy.sh: deploy script template (rsync + npm ci + systemctl + health check)
- scripts/ci-lint-fix.sh: ESLint auto-fix with [CI SKIP] commit-back
- docs/ci-cd.md: complete CI/CD documentation and troubleshooting
- .env.example: added WOODPECKER_TOKEN
