Infinite recursion when installed via pipx

[fwcd]

Running pipx install stemgen and then stemgen seems to cause infinite recursion:

Traceback (most recent call last):
  File "/Users/<user>/.local/bin/stemgen", line 10, in <module>
    sys.exit(main())
             ^^^^^^

RecursionError: maximum recursion depth exceeded

This seems to be an issue with the sys.path logic: The script seems to run from the cli/stemgen directory, but outside the repository, so it cannot find the actual stemgen.py script.

My recommendation would be to put everything under a top-level package named stemgen (so it can be installed properly), move the script implementations into the package, e.g. under stemgen.cli, and then point your entry points in setup.cfg to those functions. The top-level scripts in the repo (stemgen.py et al.) could then be simple wrappers that import the package (stemgen.cli.something) and call their main.
