feat: remove sync tests and related types for Result and ResultAsync

- Deleted the sync tests for Result and ResultAsync to streamline the codebase.
- Updated type imports in `types.ts` to reflect the removal of async-related types.
- Refactored utility functions in `utils.ts` to simplify error handling and promise checks.
