Change GameManager/CreateGame to return (gameId, gameCode) and Make JoinGame return the game Id (or null) instead of a bool. Update IGameManager signature accordingly. Refactor Hub methods to construct Player objects, accept Coordinates for game creation, use the manager results to add connections to groups and send GameCreated with GameId and GameCode, and handle join failures with an error message. Simplify Player class to use a primary-constructor style with property initialization; add necessary using directives.
Replace the nullable PlayerConnectionIds array with a private List<Player> inside Game and add AddPlayer/RemovePlayer methods to manage membership. Have GameRepository.Create attach the initial player to the newly created game. Implement GameManager.CreateGame and JoinGame to call the repository (using the injected gameRepository) — CreateGame returns the created game's code and JoinGame looks up the game and tries to add the player. Also update imports accordingly. These changes centralize player handling in the Game model and connect repository/manager flows to use it.
- Introduced `IGameRepository` interface and its implementation.
- Transitioned namespaces to `file-scoped` for consistency.
- Simplified class definitions, e.g., `Game` and `SixDigitInt`.
- Restructured `GameField` logic for improved readability and functionality.
- Fixed formatting issues in `API.csproj` and added a `using` directive in `Program.cs`.
