Contributions summary:Aleksandr primarily focused on refactoring the codebase by removing the `CheckpointManager` trait and related dependencies. This involved modifying the `StateLayout` structure and associated functions to directly handle checkpoint management. Their work involved updates to the state management logic within the Internet Computer blockchain source code and has improved overall code maintainability by removing unnecessary abstractions. The changes also appear to simplify the error handling and reduce boilerplate code.
