Integrated FatFs (R0.15) into the freestanding kernel environment. The implementation provides a bridge between FatFs and the existing hardware abstraction layer, allowing for genuine filesystem operations on USB mass storage devices discovered via CherryUSB. The VFS was updated to handle multiple mounts, and the UI now includes tools for formatting disks. All changes adhere to the "Sovereign" architecture principles, avoiding unnecessary stubs and improving upon the existing skeletal structure.
