Add W0311 to pylint ignore list for CEP-8 consistency

[coderabbitai]

Summary

Add pylint's W0311 (bad indentation) warning to the project's ignore list to maintain consistency with CEP-8 coding standards.

Background

Our project follows CEP-8 coding standards which allow tab indentation. We already ignore flake8's W191 (indentation contains tabs) in our .flake8.ini configuration. For consistency, we should also ignore pylint's W0311 warning which flags indentation that doesn't match its expected spaces-only convention.

Tasks

• Add W0311 to pylint ignore configuration
• Update CEP-8 documentation to clearly mention that W0311 should be ignored
• Verify configuration changes work as expected
