* Mark json_fwd.hpp as exported by json.hpp for IWYU / include-cleaner json_fwd.hpp is the only header declaring the nlohmann::json alias, so include-what-you-use and clang-tidy's misc-include-cleaner attributed the name to it and told users of <nlohmann/json.hpp> to include json_fwd.hpp as well (or instead, which breaks compilation). Fixes #5812 Signed-off-by: Niels Lohmann <mail@nlohmann.me> * Export the remaining client-facing headers from json.hpp and check clients with IWYU Besides json_fwd.hpp, include analyzers also told clients of <nlohmann/json.hpp> to include detail/json_ref.hpp (brace initialization), json_literals.hpp (_json, _json_pointer), adl_serializer.hpp, detail/macro_scope.hpp (NLOHMANN_DEFINE_*) and detail/abi_macros.hpp. Mark those includes as exported, too. ci_single_binaries only checked each header on its own, so it could not notice this. It now also runs IWYU and clang-tidy's misc-include-cleaner on small client programs in tests/iwyu_consumer, which fail on develop. With the exports, json_literals.hpp no longer gets the json_fwd.hpp suggestion that kept it out of the IWYU gate, so it is gated again.
