Add README, starter notebooks, and .gitignore

Add a comprehensive README that explains how to prepare a Python virtual environment, install packages, and register an ipykernel for running the lab notebooks in VS Code. Include two starter notebooks: TASK0_Datasaurus_Starter.ipynb (datasaurus warm-up with data loading, summary stats, optional SweetViz report, and faceted scatter plotting) and VisInt_Lab_01_Task_0.ipynb (lab header/metadata). Add .gitignore to exclude a local /.venv directory.

VisInt_Lab_01_Task_0.ipynb
