Docker-compatible socket. The repository must contain a
`.devcontainer/devcontainer.json`.
Herald can therefore run inside a container with only that socket mounted (no
shared workspace directory is required): the clone is streamed to the daemon over
the socket, like the build context, instead of being bind-mounted from a host
path the daemon would have to see. This is the setup the `Containerfile`
produces, e.g.:
```sh
podman run --env-file=.env -p 3001:3001 \
-v /run/user/$(id -u)/podman/podman.sock:/var/run/docker.sock \
herald:latest
```
The `runArgs` of that file are read but deliberately **not** passed to the daemon:
they come from an untrusted pull request, and one of them (`--network host`) would
attach the container to another network and quietly
