Set up unit testing for everything

[angrycaptain19]

Need to be able to automatically test new changes to ensure functionality isn't degrading as we move forward.

Set up tests and automatic test runs as part of CI

Objectives

• Set up a JavaScript testing framework (Jest or Mocha) for testing game logic
• Create unit tests for core chess game functions in chess.js including board initialization, move validation, and game state management
• Create unit tests for tic-tac-toe game logic in game.js including win condition checking and board updates
• Implement test coverage reporting to identify untested code paths
• Set up continuous integration pipeline to automatically run tests on each commit
• Create mock objects for DOM manipulation functions to enable isolated testing of game logic
• Add integration tests for game mode selection and player interaction flows
• Configure test automation in the CI pipeline to fail builds if test coverage drops below an acceptable threshold
• Document testing procedures and requirements in the repository README
• Create test fixtures for common game scenarios to improve test maintainability
