chore: add Ruff, pre-commit, Commitlint, update README

[ashishverma49]

• Ruff for Python linting
• pre-commit hooks to enforce code standards automatically
• Commitlint to standardize commit messages

Additionally, the README has been updated to document these tools, and the .flake8 file has been removed.

Part 1/1

1. Missing Error Handling: The configuration files do not include any error handling mechanisms. For example, if the pre-commit hooks fail, there is no indication of how to handle those failures or what steps to take next.

2. Security Vulnerabilities: The pre-commit-config.yaml file includes hooks from external repositories without verifying their integrity or security. This could expose the project to vulnerabilities if any of those repositories are compromised. Consider using specific versions and reviewing the code of these hooks.

3. Performance Issues: The ruff configuration includes a broad selection of rules without considering the potential performance impact on larger codebases. It may be beneficial to selectively enable only the most relevant rules to improve linting speed.

4. Logic Errors: The commitlint.config.js file enforces a "Signed-off-by" rule, which may not be appropriate for all projects. This could lead to confusion or errors if contributors are not aware of this requirement.

5. Excessive Exclusions: The exclusions in both ruff.toml and .pre-commit-config.yaml may inadvertently skip important files that should be linted or formatted, potentially allowing issues to go unnoticed. Ensure that exclusions are necessary and do not compromise code quality.
