Http Structured Fields Parser

Parse dictionary/list/item, inner lists, parameters, typed numbers/tokens/strings/bytes/booleans and RFC 9651 dates/display strings. Decimals retain exact source text; duplicate keys/parameters keep their last value in original key order. Syntax only, not field-specific semantics. 32 KiB / 1,000 nodes / 200 members / 100 inner-list items / 50 parameters.
