widgets not displaying properly when using juv on windows

[ATL2001]

I'm afraid I may have missed something with the windows support. Sadly, I'm not sure what is missing.

The notebooks work great with just code, but widgets aren't displaying properly. I tried using juv with the same notebook and it worked flawlessly on my mac. I know you know a thing or two about widgets, do you happen to have any ideas what might be needed? when I look at the extensions in jupyterlab on my mac I see jupyter-widgets-jupyterlab-manager and jupyterlab-pygments are both installed but on the windows machine I only see jupyterlab-pygments (not sure if that is relevant, but I think it may be)

Thanks for opening the issue! Sorry I haven't had the chance to look with the end of the year.

I'd kind of assumed there might be some challenges with widgets cross platform. My best guess of where the fix for this needs to be is in:

juv/src/juv/_run_template.py

Line 66 in 29e9892

SETUP_JUPYTER_DATA_DIR = """

I believe the issue comes from the fact that a single JUPYTER_DATA_DIR is used to point to the static assets required for widgets. However, uv works by layering python environments (meaning there may be multiple valid "data dirs" that we need to merge together).

My guess is that I'm doing this incorrectly for windows.
