This initial version assumes the developer has mojo_shell and all other services sitting on disk somewhere and that they're on linux and only want to run on linux. This can be generalized down the line to support more use cases. This downloads the sky_viewer.mojo corresponding to the packages/sky_engine/REVISION in the developer's directory, so they can specify whatever revision they want. sky_tools run_mojo downloads sky_viewer.mojo into its cache directory if it is not present and constructs a command line to pass to mojo_shell that maps the shebang stamped into the flx to the downloaded sky_viewer.mojo. Since sky_viewer.mojo lives in the cloud and mojo_shell can load from the cloud this could also map to an https URL. This should likely be an option.
