Doma Testnet: Core DomainFi Entities

Core entities from Doma’s multi-chain DomainFi network, designed to power trader/degen dashboards and grow over time.
Initial release includes Names, Listings, and Offers. The dataset is intentionally extensible to
add more orderbook detail (e.g., depth, fills, cancels, venue metrics) and fractionalization data (events, supply,
buyout thresholds) in subsequent versions.
