Subject: [PATCH] Install the docker CLI in jobs that build images
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The runner executes jobs inside a container that ships no docker client,
so the publish job died on its first command:

  /var/run/act/workflow/1: line 3: docker: command not found

act_runner does mount the host's socket into job containers, so only the
client is missing. Both image jobs now fetch the static binary when it is
absent and then check that the socket answers, because "no client" and
"no daemon" are different problems and the log should say which one it
hit. The docker build-test job needed the same treatment — it is skipped
on tags, so it had never reached that command either.

Verified in a container without a docker client: with the socket mounted
the step installs the client and builds the web image; without it the
step fails with the runner-configuration message instead of a confusing
connection error.
