fix: bugfix name of executable to CLI, edit (test) setup

The name of the executable to the CLI is reset to the earlier
`appendfilename`, and thus prevents collision with the one
by `guess-filename.py` (e.g., in `pipx`).  Multiple corrections
and amendments of running checks with pytest: i) retaining a
lighter `pytest.yml` to be used after each commit and push to
the GitHub repository, or as an initial check in incoming PRs
to the blessed repository.  ii) `tox.yml` to provide the
greater permutation of os runners and Python interpreters as
available to GitHub while probing with pytest -- for a manually
launched run.
