Pull request overview

This PR introduces a repository-root CLAUDE.md to provide agent guidance (build/test conventions and key architecture notes) and makes minor packaging metadata tweaks in setup.py.

Changes:

• Add CLAUDE.md with build/test instructions and project conventions for agent workflows.
• Expand setup.py package keywords to include Intel/oneAPI/oneDAL and acceleration-related terms.
• Remove the Apache 2.0 Trove license classifier from setup.py classifiers (this looks unintentional and should be restored).

File	Description
setup.py	Updates PyPI metadata keywords; license classifier removal needs correction.

Be aware that these aren't used for the PyPI packages.

Good catch - looks like GitHub Topics are more relevant for discoverability and keywords are outdated. Reverting.

what about just linking to agents.md and having single source?

Currently the CLAUDE.md is a minimal file that mentions AGENTS.md files provide more details. Or were you thinking something like a symlink?

[david-cortes-intel]

Shouldn't this instead instruct not to modify the auto-generated files like build/daal4py_cy.pyx and build/daal4py_cy.cpp? If something is wrong with those, then it should modify the files under generator/.

@ethanglaser If it's going to have a CLAUDE.md, might as well as .claude to gitignore.
