Summary

• Add .pre-commit-config.yaml with nbstripout 0.8.2 so Jupyter outputs / execution counts are stripped before commit.
• Document pre-commit install in the README.
• Normalize existing notebooks under the hook (damianou2013 Colab notebooks + examples/tutorial.ipynb).

Test plan

• pre-commit run nbstripout --all-files (second run clean)
• pip install pre-commit && pre-commit install then commit a notebook with outputs and confirm they are stripped
