✨ feat: Add SuiBets — decentralised P2P sports betting on Sui blockchain

[elpou88]

SuiBets Exchange Connector

SuiBets is a decentralised P2P sports betting dApp on the Sui blockchain. This PR adds it as a new pmxt exchange, making all P2P bet offers queryable through the unified pmxt API.

How it maps to pmxt concepts

pmxt concept	SuiBets equivalent
UnifiedMarket	A P2P bet offer (one creator vs one taker side)
UnifiedEvent	A sports match (groups all offers for that fixture)
Outcome YES	Creator's pick (e.g. "Real Madrid wins")
Outcome NO	Opposite side (taker's pick)
price	Implied probability derived from the offer odds
liquidity	Remaining creator stake available to be filled
contractAddress	On-chain Sui object ID (when using on-chain escrow)

Usage

import pmxt from 'pmxtjs';

const exchange = new pmxt.SuiBets();

// List all open P2P offers as markets
const markets = await exchange.fetchMarkets({ limit: 20 });

// Group by match (event)
const events = await exchange.fetchEvents({ query: 'Real Madrid' });

// Fetch order book for a specific offer
const book = await exchange.fetchOrderBook('offer123:creator');

// Fetch user positions (requires wallet)
const ex2 = new pmxt.SuiBets({ walletAddress: '0xabc...' });
const positions = await ex2.fetchPositions();

What's on-chain

SuiBets uses the Sui blockchain for escrow. When isOnchain: true, the creator stake is locked in a Move smart contract (contractAddress = Sui object ID). Settlement is fully on-chain — no house, no custody.
