[Unit Tests] Create unit tests for GameState

Feature Request

Summary

Create unit tests for the GameState class to validate referee updates, world‐state updates, score tracking, and orientation flags.

Acceptance Criteria

• Add GameStateTest.cpp under unit_tests.
• Test updateRefereeState(refData) changes internal gameState and getRefereeData().
• Test updateWorldState(ballData, friendlyTeam) sets isBlueOnPositive() flag and updates ball.
• Test getBlueScore()/getYellowScore() after sequential calls.
• Test isBlueOnPositive() toggles based on input.
• Test getRefereeState() reflects last referee command.
• All tests compile under Ninja and pass via ./build/unit_tests.

Design / Technical Approach

1. Include GameState.h, stub RefereeData.
2. Feed sample referee data, assert state changes.
3. Feed world‐state updates, assert orientation and scores.

Dependencies

• GameState.h, RefereeData.h, BallData.
• Boost.UT framework.

Testing Plan

• Build:

  ninja

• Run:

  ./build/unit_tests --run_test GameState
