Add include guards to header files and update Makefiles

Replaced #pragma once with explicit include guards in all header files for consistency and portability. Renamed and reorganized several headers for better structure. Refactored Makefile logic to remove Extra.mk, add CppOps.mk and Timestamp.mk, and centralize object file generation in lib/Objects.mk. Updated Makefiles to use new includes and improved build directory handling.
