* Re-amalgamate single_include/json.hpp

The previous commit updated the split headers but the amalgamated
file didn't go back through astyle before I committed it, so CI's
amalgamation check caught formatting drift in json_fwd.hpp and a
few noexcept clauses in basic_json, plus one doc example. None of
it touches the UBJSON logic. Applied the patch CI generated to
bring single_include back in sync.
