Changelog

Daangn realty operations now use the current realty GraphQL surface, return canonical realty article URLs, declare the current map filter contract, and expose normalized Korean realty labels plus richer article quality fields for easier client filtering and display

This change restores Daangn realty reads after the upstream realty route moved away from the legacy Remix _data contract. The provider now resolves the region, fetches map clusters and article cards through Daangn realty GraphQL, applies optional keywords over normalized article text and Korean labels, and returns canonical https://realty.daangn.com/articles/<id> URLs
