Gourab Panigrahi ❯ Difference between matrix free .cc files in dftfe/src/matrixfree and dftefe/electrostics except the namespace difference

⏺ The key substantive differences (beyond namespace) are:

1. BLASWrapper completely removed from MatrixFree

• BLASWrapperPtr constructor parameter removed from MatrixFree, MatrixFreeWrapperClass
• d_BLASWrapperPtr member removed from MatrixFree
• BLASWrapper.h not copied into dft-efe at all

1. Include restructuring

• <headers.h> (dftfe umbrella include) → explicit <deal.II/...> and <utils/...> includes
• <BLASWrapper.h>, <DeviceTypeConfig.h>, <DeviceExceptions.h>, <DeviceKernelLauncherHelpers.h> removed from MatrixFreeDevice.h
• Angle bracket includes (<MatrixFree.h>) → quote includes ("MatrixFree.h") for local headers

1. Type change (dftfe::uInt → dftefe::uInt) — which you already did

Everything else is just namespace renaming.
