feat(ts-sdk): add SuiNS and channel name resolution for human-readable identifiers

[arbuthnot-eth]

Summary

This PR adds human-readable naming support to the Sui Stack Messaging SDK, enabling users to reference addresses and channels by name instead of raw object IDs.

Features

• SuiNS Integration (@user.sui): Resolve SuiNS names to Sui addresses
• Channel Names (#channel): Map human-readable names to channel object IDs

API

Address Resolution (SuiNS)

import { SuinsClient } from '@mysten/suins';
import { messaging, SuiNSResolver } from '@mysten/messaging';

const suinsClient = new SuinsClient({ client: suiClient, network: 'mainnet' });

const client = suiClient.$extend(messaging({
  addressResolver: new SuiNSResolver(suinsClient),
  // ...
}));

// Use SuiNS names directly
await client.messaging.executeCreateChannelTransaction({
  signer,
  initialMembers: ['alice.sui', 'bob.sui', '0x123...'],
});

Channel Name Resolution

import { messaging, LocalChannelRegistry } from '@mysten/messaging';

const channelRegistry = new LocalChannelRegistry();
await channelRegistry.register('general', '0xchannel123...');

const client = suiClient.$extend(messaging({
  channelResolver: channelRegistry,
  // ...
}));

// Use channel names
const members = await client.messaging.getChannelMembers('#general');
const messages = await client.messaging.getChannelMessages({
  channelId: '#general',
  userAddress: '0x...',
});

Exports

// Address resolution
export { SuiNSResolver, isSuiNSName } from '@mysten/messaging';
export type { AddressResolver } from '@mysten/messaging';

// Channel resolution
export { 
  LocalChannelRegistry, 
  PersistentChannelRegistry,
  isChannelName, 
  normalizeChannelName, 
  formatChannelName 
} from '@mysten/messaging';
export type { ChannelNameResolver } from '@mysten/messaging';

Breaking Changes

• createChannelFlow() is now async (returns Promise<CreateChannelFlow>)

Test Plan

• pnpm build - TypeScript compilation passes
• pnpm test:typecheck - Type checking passes
• pnpm test:unit - 61 unit tests passing (21 address + 40 channel)
• Integration tests with SuiNS testnet names

• Enables human-readable UX for decentralized messaging
• Foundation for agent addressing (e.g., @summarizer.sui)
