Merge branch 'main' into hanif/using-dead-cleanup

Remove Unused Usings and the Includes Kept Only for Them
151 using-directives, using-declarations, type aliases and namespace aliases in source and test files that nothing refers to: the name is never used, it duplicates a using already in scope, or the code sits inside the namespace it names. Each one was removed on its own and the file still compiled, both as it is and with every header-level using taken away, so none of them was only redundant because a header leaks the same name. With the using gone, 28 #include lines and one forward declaration had no other reference left in their file (boost/optional.hpp without any optional, property_tree headers without any ptree) and go with it. No header is touched.
