meta/logic.hpp added a second set of type-level boolean helpers (cxpr_and, cxpr_or, cxpr_not, ...) next to the existing conjunction and negation in type_traits.hpp. It was used only by one static_assert in from_json_tuple_impl, two of its templates were never used, and it was the only header without the license banner and relied on transitive includes for <type_traits>. Add the missing disjunction next to conjunction and negation, use the three in the static_assert, and delete logic.hpp together with its BUILD.bazel entry. same_sign now uses disjunction as well, which resolves the 2022 TODO waiting for such a trait. The static_assert accepts and rejects the same types as before. Only names in nlohmann::detail change; behavior, public API and ABI are unchanged.
