[WIP] Add GitHub workflow to run pytest

[Copilot]

Plan: Add GitHub Workflow to Run Pytest

• Create .github/workflows directory structure
• Create GitHub workflow YAML file to run pytest
  • Set up workflow to trigger on push and pull_request events
  • Configure Python 3.8+ (as per pyproject.toml requirements)
  • Install pytest dependencies using pyproject.toml dev dependencies
  • Run pytest command (relies on pyproject.toml configuration)
• Test the workflow configuration locally (validate YAML syntax)
• Address code review feedback
  • Use pip install -e .[dev] to install dev dependencies from pyproject.toml
  • Remove redundant -v flag (already configured in pyproject.toml)
• Verify all changes are minimal and focused
