Detailed Description

Program-wide registry of every tag-value kind that opts in via the TAGVAL_REGISTER_KIND macro.

This is distinct from OpenEndedRegistry<Owner> in <tagval/openended_registry.hpp>, which is per-OpenEnded-kind storage of extern-entry pointers. KindRegistry indexes kinds — both ClosedEnded and OpenEnded — and is intended for tools that want to enumerate the full set of tag-value kinds in a program (API documentation, OpenAPI emitters, debug/admin endpoints, etc.).

Registration is opt-in via the TAGVAL_REGISTER_KIND macro (declared in <tagval/macros.hpp>); a kind that is never registered does not appear in the registry even if it is otherwise used in the program.

Concurrency model mirrors OpenEndedRegistry: mutation only happens during static-init (single-threaded by contract); reads after main() are safe for concurrent readers.
