Modularize noxfile.py #3128
Description
Description of improvement
We should consider extracting complicated sessions from noxfile.py and putting them into standalone scripts in tools/. This would best be done for sessions that are not used in CI, and thus exclude sessions like tests, docs, etc.
Motivation
Extracting scripts would have a few benefits:
- Decouple these tasks from Nox, in case we switch to a different task runner in the future.
- Make
noxfile.pyeasier to navigate. - Improve cohesion for each of the files.
Implementation strategy
The best place for the scripts would probably be tools/.
We should embed metadata in them (as per PEP 723) so that we can run them with uv run.
The sessions could still be kept in noxfile.py to make it easier to use a matrix setup for GitHub workflows, while also making them easier to find (with nox -l) and run (with nox -s '<session_name>'). The new sessions could be something like session.run("uv", "run", "scriptname.py").
