Subject: [PATCH] Add CI that catches syntax errors and undefined names

The code here needs hardware or large models, so there are no tests to run.
The workflow compiles every Python file and runs flake8 with only the checks
for errors that crash at run time (E9, F63, F7, F821-F823). --isolated keeps
flake8 from reading any [flake8] section in setup.cfg.
