Add player controller, state management, and input handling
- Implemented PlayerController.cs to manage player movement and actions. - Created PlayerState.cs to track player lives, coins, and key status. - Added CameraFollow.cs for smooth camera movement following the player. - Developed Character.cs as an abstract class for character behavior. - Introduced Enums.cs for defining TreasureType and MapElementType. - Added IDoor interface for door interactions. - Created InputActions.cs for handling player input actions. - Implemented MainMenu.cs for basic menu functionality including play and exit options.
