Problem:
Scripts named with 'python-…' prefix may not be valid python bins. If
such a script is found in a venv, the Python healthcheck fails hard.
.venv/python-argcomplete-check-easy-install-script
.venv/bin/python3.13
.venv/bin/python
Solution:
- Discard known false-positives such as `python-argcomplete*`.
- Call `health.warn()` instead of `assert()` in `python_exepath()`.
