/**
 * Gets the ENSIP-19 default (chain-agnostic) primary names for a batch of
 * addresses by reading the `DefaultReverseResolver`'s `resolveNames`.
 *
 * This is the ENSIP-19 `default.reverse` resolver from `ens-contracts` (not a
 * v2-specific contract — ENSv2 has no reverse resolver of its own). It is read
 * directly because {@link getName} goes through the Universal Resolver's
 * per-coin reverse lookup (defaulting to coinType `60`, i.e. `addr.reverse`),
 * which does not surface the chain-agnostic `default.reverse` records this
 * resolver holds.
 *
 * Note: results are NOT forward-verified. Callers that need a verified primary
 * name should check forward resolution themselves.
 *
 * @param client - {@link Client}
 * @param parameters - {@link GetNamesParameters}
 * @returns Names aligned to `addresses` (`null` where no name is set). {@link GetNamesReturnType}
 *
 * @example
 * import { createPublicClient, http } from 'viem'
 * import { sepolia } from 'viem/chains'
 * import { addEnsContracts } from '@ensdomains/ensjs'
 * import { getNames } from '@ensdomains/ensjs/public'
 *
 * const client = createPublicClient({
 *   chain: addEnsContracts(sepolia),
 *   transport: http(),
 * })
 * const result = await getNames(client, {
 *   addresses: ['0xb8c2C29ee19D8307cb7255e1Cd9CbDE883A267d5'],
 * })
 * // ['nick.eth']
