This is necessary in two cases: * On POSIX, the exe path (`argv[0]`) must contain a path separator * Some programs might treat a file named e.g. `-foo` as a flag, which can be avoided by passing `./-foo` Rather than detecting these two cases, just always include the prefix; there's no harm in it. Also, if the cwd is specified, include it in the manifest. If the user has set the cwd of a Run step, it is clearly because this affects the behavior of the executable somehow, so that cwd path should be a part of the step's manifest. Resolves: #24216
