static constexpr name reflection

[stephenberry]

Summary

Fixes issue #2327: implicit key inference now works for static class members (for example static constexpr std::string_view) when used in glz::object(&T::member, ...).

Changes from main

• include/glaze/reflection/get_name.hpp
  • Added name extraction support for object pointers in get_name, so static members can be reflected without requiring explicit key strings.
  • Refactored shared pretty-function parsing into small helper functions to keep member-pointer and pointer paths consistent.
