Environment Check

Run the environment check script and report results to the player in a friendly way:

bash engine/environment-check.sh

After the check:

All Passed

Tell the player they're all set. If this is during game start, continue to the game.

Some Warnings

Explain which optional tools are missing and when they'll need them:

kubectl + kind: "You won't need these until Chapters 6-7 (Kubernetes). You can install them later!"
curl: "Some challenge verifications use curl. Most things still work without it."

Failures

Guide the player to fix each failure:

Docker not installed → Link to https://docs.docker.com/get-docker/
Docker not running → "Start Docker Desktop" or
```
sudo systemctl start docker
```
Docker Compose missing → Link to https://docs.docker.com/compose/install/

$ARGUMENTS

contains "--full", also check:

Docker can pull images:
```
docker pull hello-world
```
Docker can run containers:
```
docker run --rm hello-world
```

Docker networking works:

docker network create learn-test && docker network rm learn-test

Be encouraging — don't make missing optional tools feel like failures.
