TDD Workflow for Tetris Game

Test-driven development guidance following the project's strict TDD requirements.

TDD Principles

1. Test First: Write tests before implementation
2. Red-Green-Refactor: Fail → Pass → Improve
3. Co-located Tests: Test files must be next to implementation (*.test.ts)
4. 160+ Tests: Comprehensive coverage for all game logic
5. Property-based Testing: Use fast-check for critical game mechanics

Test Execution

# Run all tests (160+ tests)
bun test
