[StasJ]

Fix #3802 by moving OSGL context handling to VAPI. Also adds support for Marimo notebooks. All of Vapor's example jupyter notebooks are now also included as Marimo notebooks.

Hey Stas, I'm still getting a dead kernel with Jupyter on Casper with the referred linux-64 installer. How can I verify that this build was with your latest changes for the PythonAPI? I'm at 3.11 but I'd like to know how to ascertain the commit hash.

Screenshot and console error below.
