main: require argv[0]
sure, linux has been providing argv[0] by default for a while now. other OSes may not be as forthcoming though, and relying on the OS to create a world in which we can just make assumptions we could test for instead is unnecessarily lazy. we *could* default argv0, but that's a little silly. notably we abort instead of returning normally to avoid confusions where a caller interprets our exit status like a Worker build results bitmask.
