Adding an open-source license

[yolomax]

Hi, thank you for sharing this great project! I noticed that the repository currently doesn’t include a license file. Adding an open-source license (such as MIT, Apache 2.0, or GPL) would clarify how others are allowed to use, modify, and distribute the code.

Including a license would also make it easier for others to build on your work while ensuring legal compliance.

Thanks again for your efforts, and looking forward to your response!
