Add GPL License for Open Source Compilance

[sreevidya-16]

Description

I propose adding a GPL (GNU General Public License) to this repository to ensure it adheres to open source licensing standards.

Issue Details:

📝 Lack of License: Currently, this repository does not have a license specified.
📜 Open Source Compliance: Adding a GPL license will make the project legally compliant with open source requirements and clearly define usage terms.

Proposed Solution:

🏷️ Add GPL License: Implement the GNU General Public License (GPL) to protect both contributors and users, ensuring the project remains free and open source.
📂 License File: Create a LICENSE file in the repository root with the full text of the GPL.
