refactor(core): move AsarWrapper to core directory and update includes

- Relocated AsarWrapper implementation and header files from `src/app/core/` to `src/core/` to enhance modularity and organization.
- Updated all relevant include paths across the codebase to reflect the new location of AsarWrapper.
- Adjusted CMake configurations to ensure proper compilation of the core library.

Benefits:
- Improves project structure by separating core functionalities from application-specific code.
- Facilitates easier maintenance and understanding of the codebase by clarifying the organization of core components.
