TODO Before Asking for a Review

• Rebase your branch to the latest version of dev (or main for release PRs)
• Make sure all CI workflows are green
• When adding a public feature/fix: Update the Unreleased section of CHANGELOG.md (no date)
• Self-Review: Review "Files Changed" tab and fix any problems you find
• API Docs (only if there are changes in docstrings, rst files or samples):
  • Check the docs build without warning: see the log of the API Docs workflow
  • Check that your changes render well in HTML: download the API Docs artifact and open index.html
  • If there are any problems it is faster to iterate by building locally the API Docs

LGTM, but:

• we need to take a look at the api-docs workflow execution log and check that there are no build warnings, then download the build artifact locally and visually inspect the rendered result via python -m http.server for instance;
• we need to check the results of the (manually launched) workflows conda and pip - check that the build and test jobs succeed;
• [debatable] we need to manually launch the expensive tests in the tests workflow.

The latter points have been done and:

• pip and conda succeed
• tests is executing: https://github.com/KhiopsML/khiops-python/actions/runs/20996393286
