- Add all 20 eks-module terragrunt.hcl files to templates/eks-modules/;
  these are written verbatim (file()) into the generated repo under
  $env/$region/$vpc/$cluster/<module>/terragrunt.hcl
- Wire templates/eks-modules/ into managed_extra_files via a fileset-based
  local (eks_module_files) merged with the existing rendered_files local
- Set template_repo = null in both defaults.tf and main.tf; all generated
  repo content now flows exclusively through managed_extra_files with no
  GitHub template seeding
- Rename templates/common-variables.hcl and templates/default-versions.hcl
  to *.hcl.tf.tpl to match the existing convention: .tf.tpl = parsed by
  templatefile(), eks-modules/*.hcl = written verbatim
- Update locals.tf references for the renamed template files
- Fix alignment formatting in examples/basic and examples/adsd-tools-dev
