Docker Compose requires the test array to start with NONE, CMD, or CMD-SHELL.
The previous example was missing the prefix, so Compose treated the binary
path as the shell command, the healthcheck was rejected, and the container
was marked unhealthy — which causes Traefik (and similar) to skip it.
Closes#535
