### 新 broker-cancel-refund.js (97 LOC)
```js
detectCancelIntent(message) → bool
  // regex: NO/不要了/不要啦/取消(订单)?/算了(吧)?/退(我|回)?(钱|币|KAS|USDT|USDC)?/
  //        我不(要|做|玩|交易)了?/不卖了?/不买了?/cancel(\s+order)?/refund/
  //        give\s+(me\s+)?(my\s+)?(money|kas|usdt|usdc)\s+back

handleCancelAndRefund(peerAddr) → string|null
  // 1. SELECT exchange_offers WHERE maker=BROKER + metadata.user_kasia=peer
  //    + protocol_status='open' + taker IS NULL + broadcast_at > now-3h
  // 2. for each refundable:
  //    - POST /api/exchange/cancel (broker maker cancel + cancel_v1 上链)
  //    - enqueue sendKas refund = intent_qty - 0.1 (broker fee)
  //    - INSERT events 'user_cancel_refund' audit log
  // 3. return ack: '✓ 订单 X 已取消, X KAS 退还中 (扣 0.1 broker fee), 1-2min 到账'
  // 4. 没命中 (无 refundable) → null fall through
```

### Wire 3 handler 同模式 (detectResetIntent path 后)
- broker-buy-handler.js handleBuyIntent 入口
- broker-sell-handler.js handleSellIntent 入口
- broker-llm-agent.js handleLlmDialog 入口

边界 (本 PR scope):
- 仅 open + taker=null → 单方撤+退
- matched/verifying/delivering → 走 dispute (不动)
- KAS 退已实现; USDT/USDC 退 P2 (现 BUY 流程 broker 不持 stable)

## Verify
- ✓ syntax OK 4 files
- ✓ lint-kanet ✓ 4 files clean
- ✓ pre-commit ✓
- ✓ console restart 加载新代码 (PID 重起后 ready 1s)
- ✓ smoke test: synthetic peer 'NO' → cancel-refund 检不到 active offer → null → fall through (no crash)

## Owner 88 KAS DM 真测 path

Owner DM Trader-B 'NO' / '取消' / '不要了' / '退我钱' / '我不卖了' 任一:
1. detectCancelIntent → true
2. handleCancelAndRefund(Owner Kasia) → 找到 6ac84b51 matches
3. POST /api/exchange/cancel: protocol_status='cancelled' + cancel_v1 broadcast 上链
4. enqueue sendKas: 87.9 KAS → Owner Kasia (intent_qty 88 - fee 0.1)
5. enqueue events 'user_cancel_refund' audit
6. broker reply '✓ 订单 6ac84b51 已取消, 87.9 KAS 退还中 (扣 0.1 broker fee), 1-2min 到账你的钱包.'

Owner 可以**真测真验** cancel-refund 政策 + 真**真**真**收到** 87.9 KAS。

## J1/NWT

J2 standby Owner 真测后 NWT 写 case lifecycle_user_cancel_refund_v1 守 regression。
