Enhancement: Add Scoreboard and Improve Game State Management

[Tithi234]

Description

The current Tic Tac Toe implementation does not track player scores across multiple rounds and relies heavily on global variables for game state management.

Proposed Improvements

• Add a persistent scoreboard to track wins for Player 1 and Player 2.
• Improve game state handling by reducing reliance on global variables.
• Refactor win detection logic for better maintainability.
• Improve user experience by showing score updates dynamically.

Why This Matters

Adding a scoreboard enhances gameplay experience and makes the application more feature-complete. Refactoring state management improves code readability and extensibility.

I would like to work on this enhancement.
