Update requirements to include Python 3.13

Mostly everything is the same. Scipy needed to be special-cased in the pyproject.toml, but nothing crazy.

Note: We should probably start shifting Python 3.9 to deprecated...

I think it should all be ready now. Summary:

1. scipy and numpy special-casing for Python 3.9
2. Pinning poetry 1.8.4
3. Using Matplotlib with Agg backend to avoid interactivity (esp. for Windows)

Google Colab is already on Python 3.12. I think we may consider preempting 3.14 (and deprecating 3.9 and upgrading to Poetry 2+)

I verified with my own poetry update on my system and it matched what you got.
