Release the binary for the Docker CLI plugin `docker-model-plugin`

• The documentation at https://docs.docker.com/ai/model-runner/get-started/#docker-engine only mentions how to install the docker-model-plugin on a rootful Docker engine. However, it never mentions how to install the docker-model-plugin on a rootless Docker engine.

• It seems that currently, Git only releases source code, not binary artifacts. This prevents me from performing operations like the following:

sudo apt install --assume-yes uidmap iptables
cat /etc/systemd/system/user@.service.d/delegate.conf
sudo mkdir -p /etc/systemd/system/user@.service.d

sudo tee /etc/systemd/system/user@.service.d/delegate.conf << EOF
[Service]
Delegate=cpu cpuset io memory pids
EOF

sudo systemctl daemon-reload
mkdir -p ~/bin
curl -L -o /tmp/docker.tgz "https://mirrors.aliyun.com/docker-ce/linux/static/stable/x86_64/docker-29.6.1.tgz"
tar -xzf /tmp/docker.tgz --strip-components=1 -C ~/bin
curl -L -o /tmp/rootless.tgz "https://mirrors.aliyun.com/docker-ce/linux/static/stable/x86_64/docker-rootless-extras-29.6.1.tgz"
tar -xzf /tmp/rootless.tgz --strip-components=1 -C ~/bin
rm /tmp/docker.tgz /tmp/rootless.tgz

tee --append ~/.bashrc <<'EOF'
export PATH=$HOME/bin:$PATH
EOF

source ~/.bashrc
~/bin/dockerd-rootless-setuptool.sh install
cat ~/.config/docker/daemon.json
mkdir -p ~/.config/docker

tee ~/.config/docker/daemon.json <<EOF
{
  "log-driver": "local"
}
EOF

systemctl --user restart docker.service
ls -la ~/.docker/cli-plugins/
mkdir -p ~/.docker/cli-plugins
curl -L -o ~/.docker/cli-plugins/docker-buildx https://github.com/docker/buildx/releases/download/v0.35.0/buildx-v0.35.0.linux-amd64
chmod +x ~/.docker/cli-plugins/docker-buildx
curl -L -o ~/.docker/cli-plugins/docker-compose https://github.com/docker/compose/releases/download/v5.3.1/docker-compose-linux-x86_64
chmod +x ~/.docker/cli-plugins/docker-compose

• I think the binary output of the Docker CLI plugin docker-model-plugin should be released so that I can download it into the ~/.docker/cli-plugins folder.

The issue concerns the docker-model-plugin binary and installation into ~/.docker/cli-plugins. Start by tracing how this repository’s GitHub releases currently publish source-only artifacts; done means a downloadable plugin binary is available for the requested Docker CLI installation path and the rootless-engine installation guidance is addressed.
