Description

Moved flake8 settings from setup.cfg to tox.ini thus eliminating setup.cfg completely.

Motivation and Context

• This eliminates the need to have setup.cfg file.
• since flake8 settings can be maintained in tox.ini, there is no need to maintain a separate config file which is setup.cfg just to maintain flake8 settings.
• We can accommodate flake8 settings in tox.ini and can completely get rid of setup.cfg file

Types of changes

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to change)

PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Score
Maintainability	Add explanatory comments for flake8 error code suppressions to improve configuration maintainability Consider adding a comment explaining why E203 is ignored, as it's not immediately clear why this error code needs to be disabled. py/tox.ini [65] +# E501: Line too long (handled by black) +# E203: Whitespace before ':' (conflicts with black) extend-ignore = E501, E203 Apply this suggestion Suggestion importance[1-10]: 5 Why: Adding explanatory comments for ignored error codes improves maintainability by making it clear why certain flake8 rules are disabled. While helpful for documentation, this is a moderate-impact suggestion focused on code clarity rather than functionality.	5
