Add Pre-commit Support for Code Quality Assurance

### Description:

To ensure consistent code quality and style across the repository, I propose adding pre-commit support. Pre-commit hooks can help automate several tasks before commits, such as code formatting, linting, and running basic tests.

### Benefits:

1. **Consistent Code Style**: By using tools like `black` or `yapf`, we can ensure that the codebase has a consistent style, making it more readable and maintainable.
2. **Catch Issues Early**: Linters like `flake8` or `pylint` can catch common Python mistakes before they're committed.
3. **Automate Processes**: Instead of manually running formatters or linters, developers can rely on these tools to run automatically, ensuring that only quality code gets committed.
4. **Reduce Review Overhead**: With automated checks in place, code reviewers can focus on the logic and structure of the code rather than style or basic issues.

### Proposed Steps:

1. Add a `.pre-commit-config.yaml` file to the root of the repository.
2. Define the desired hooks, such as `black`, `flake8`, etc.
3. Update the `README.md` or contributing guidelines to instruct developers on how to set up pre-commit in their local development environment.
4. Optionally, integrate with CI/CD to ensure that commits and PRs adhere to the defined hooks.

I believe that adding pre-commit support will significantly enhance our development workflow and ensure a higher code quality standard. Looking forward to feedback on this proposal!
