Trade prediction market outcomes on Polymarket's CTF Exchange.

## Planned Implementation

### Market Interaction

```typescript theme={null}
import { Polymarket } from './Polymarket.js';

const poly = Polymarket({
  provider,
  ctfExchange: CTF_EXCHANGE_ADDRESS,
});

// Get market info
const market = await poly.getMarket(conditionId);
console.log('Outcomes:', market.outcomes);
console.log('Prices:', market.prices);

// Buy outcome tokens
await poly.buy({
  conditionId,
  outcomeIndex: 0, // YES
  amount: parseUnits('100', 6), // 100 USDC
  minOutcomeTokens: parseEther('150'),
  signer,
});
```

### Order Book

```typescript theme={null}
// Place limit order
await poly.placeLimitOrder({
  conditionId,
  outcomeIndex: 0,
  side: 'BUY',
  price: 0.65, // 65 cents
  size: parseUnits('100', 6),
  signer,
});

// Cancel order
await poly.cancelOrder({ orderId, signer });
```

### Redeem

```typescript theme={null}
// Redeem winning outcome tokens after resolution
await poly.redeemPositions({
  conditionId,
  indexSets: [1], // Outcome 0 won
  signer,
});
```
