* Add pre-push hook for npm ci validation
Catches lock file drift locally before it breaks CI. Includes
install instructions in git-workflow.md.
* Add repo provisioning script
Automates the new-repo checklist: GitHub repo creation, OIDC deploy
role, repo secret, security features, CI/CD workflow stubs, and
pre-push hook installation. Supports both SAM and CDK stack types.
* Add shared VpnEc2Instance CDK construct
Reference construct for the VPN-accessible EC2 pattern used by
file-share and forgejo. Includes VPC/subnet lookup, SG, IAM role,
encrypted EBS, and DLM snapshots. Copy into lib/constructs/.
* Add post-deploy health check template
Template script for project-specific health checks. Copy to
scripts/health-check.sh — CD workflows run it automatically.
