Terragrunt v0.77+ warns about using terragrunt.hcl as root config.
Rename to root.hcl and update all child includes to use
find_in_parent_folders("root.hcl").

Keep existing git.fxhnt.ai hostname for GitLab CE (repoint DNS
to new Tailscale IP after deploy). Add Terraform DNS module to
manage the A record via Terragrunt instead of manual scw CLI.
