ci: Implement CI/CD pipeline for Python project

[SoClosee]

This PR introduces a CI/CD pipeline using GitHub Actions for a Python project. The pipeline includes:

• Build and Test: Runs tests on multiple Python versions (3.8, 3.9, 3.10) to ensure compatibility.
• Dependency Caching: Caches pip dependencies to speed up the build process.
• Timeouts: Sets timeouts for each job to prevent them from running indefinitely.

The deployment step is configured to run only on pushes to the main branch and requires an API key stored in GitHub Secrets.
