feat(dev-workflow): add Perl/Python/Go/Ansible/Terraform/Podman config

- cperl-mode with perltidy formatter and LSP
- Python with ruff formatter and pyright LSP
- Go with gopls and goimports
- Ansible/YAML with ansible-lint
- Terraform with terraform-ls LSP
- Dockerfile/Podman with hadolint
- SPC m f/r/t/b/d keybindings per language
