Count Hermes run as a module from an activated venv as Hermes too

With the venv active, a gateway started by hand is `python -m hermes_cli.main gateway run`: the interpreter is bare, the executable resolves outside the runtime, and no runtime path is on the command line, so the removal took it for a stranger and refused over the files it holds rather than closing it. Hermes's own package named with -m is the program.
