Add requirements.txt for version management

[chenfei8888]

Description:
I need a requirements.txt file (or similar dependency management file like Pipfile/pyproject.toml) to be added to this project. Currently, without clear version specifications for Python dependencies, it's difficult to:

Reproduce the development environment - New contributors cannot easily set up the project with compatible library versions

Avoid version conflicts - Different library versions may cause unexpected behavior or breaking changes

Ensure consistent installations - Without pinned versions, CI/CD pipelines and deployments may use different dependency versions

Thanks, Yiyang Huang will try to attend this later.
