EasyEnv CLI v0.5.0

chore(examples): install make alongside other build deps

flask, kubespray, and postgres-cluster examples assume `make` is
available; install it explicitly so the workspaces are reproducible
on a clean Ubuntu base.

EasyEnv CLI v0.4.0

chore: initial repo scaffolding

Sample projects + CLI reference for easyenv.io.

- README + docs/ (install, commands, workspace-yml, stacks)
- examples/ (ubuntu, docker-image, docker-compose, flask, git-repo,
  airflow, kubespray, postgres-cluster, argocd) — each with its own
  README and a validated .easyenv/workspace.yml
