Run a container

Create and start a container from a `RunSpec`. Requires the **operator** role, or the **admin** role when the spec reaches the host through a host path in `volumes`, any `mounts`, `devices`, or `extraArgs`, an escalating capability in `capAdd`, or a shared host namespace such as host networking. Mounting the host root is refused for every role, and so is sharing a host namespace on OrbStack.
