HTTP request to the gateway, plus the host-side constants that drive it
through :meth:`BackendBase.exec_shell`.

Flow: host spawns ``python3 -c <SHIM_SCRIPT> ...`` via ``exec_shell``;
the shim calls the gateway's loopback port using ``urllib.request`` and
emits one JSON envelope on stdout::

    {
        "status": <int>,                  # HTTP status, or -1 on error
        "body":   "<base64-of-bytes>",    # inline when small
        "body_file": "<sandbox-path>",    # spilled when > inline_limit
        "error":  "<short message>"       # only when status == -1
    }

The gateway listens only on the sandbox's loopback; the host has no
network reachability to it. The shim relies on ``python3`` (which the
gateway venv already needs) rather than ``curl`` because we cannot
assume ``curl`` on every backend image.
