Changelog

Daangn Marketplace search and realty price-history inputs now use APIFuse facade names for availability and transaction filters.

This release completes a Daangn Marketplace contract standardization pass after the facade hardcut.

Replace only_on_sale with available_only on used-goods-search, realty-search-listings, and cars-search. Replace chart_trade_type with trade_type on realty-complex-price-history. Opaque ids, canonical URLs, normalized item envelopes, and read-only behavior are unchanged.
