C++ Reflection via Clang LibTooling
summary
A Clang LibTooling-based tool parses the Clang AST and emits generated metadata headers that define a reflect function returning a specialization of a metadata_instance for each struct/class. The metadata fills a data_members tuple of name/reference bindings so code uses std::apply to run a recursive serialize that prints JSON. The tool consumes compile_commands.json plus file list, updates headers when types change, and supports nested types; future work targets richer AST nodes like namespaces and classes.
