Add test job to CI/CD pipeline before build

[ImChong]

Summary

This PR adds a dedicated test job to the GitHub Actions deployment workflow that runs before the build job, ensuring code quality and test coverage are validated before building artifacts.

Key Changes

• Added a new test job that runs on Ubuntu latest
• Configured Python 3.12 environment setup
• Installed development dependencies from requirements-dev.txt
• Added Ruff linting checks for scripts/ and tests/ directories
• Added Pytest test execution with verbose output
• Updated the build job to depend on the test job completing successfully

Implementation Details

The test job is configured to run before the build job using the needs: test dependency, ensuring that:

• Code passes linting checks (Ruff)
• All tests pass (Pytest)
• Build only proceeds if tests succeed

This improves CI/CD reliability by catching issues early in the pipeline.
