refactor: use Box to store large config objects and add memory usage tests

- Refactored config-related structs to use Box for storing large objects (e.g., IRuntime, IProfiles, PrfItem) to reduce stack memory usage and improve performance.
- Updated related methods and assignments to handle Boxed types correctly.
- Added and improved unit tests to compare memory usage between Boxed and non-Boxed config objects, demonstrating the memory efficiency of Box.
- Test output now shows the size difference between stack-allocated and heap-allocated (Box) config objects.
