Check whether a DNS change has reached the configured public resolvers
Check whether a DNS change has reached the configured public resolvers. Compare public DoH answers with an optional expected answer set and return complete, partial, not_observed or unknown. Scope is a fixed bounded resolver set; Forest does not claim worldwide propagation. Base mainnet USDC
