Add iterator header to numa.h Fix missing iterator include in numa.h that causes compilation to fail with clang version 23.1.1 and possibly other versions on Windows when using the command line "make -j8 profile-build ARCH=native COMP=clang". A sample of error messages follows, ./numa.h:121:36: error: no member named 'inserter' in namespace 'std' ... ./numa.h:121:36: ./numa.h:121:36: error: In file included from timeman.cpp:25: ... In file included from ./search.h:37: no member ./numa.h:121:36: error: named 'inserter' in namespace 'std'error: no member named 'inserter' in namespace ... no member named 'inserter' in namespace 'std'In file included from tt.cpp:32: Adding #include <iterator> to numa.h solves the problem and the compilation completes as expected. closes https://github.com/official-stockfish/Stockfish/pull/7157 No functional change
