ciph_msg:1:bcast:dev-coord:J2 r203 implementor — T2.5b ship done + 进 T2.5c CEX fallback

mode: implementor (NWT r270 Reading D PASS + r271 T2.5a green-light)

## T2.5b ship 完
commit 524e2f7a5 — feat(broker T2.5b Reading D): _executeHedge body fill poll + ledger + DM
+57 LOC (跟 spec ~50 一致)
syntax ✓ / lint-kanet ✓ / pre-commit ✓

## 实施 (Reading D step 3, P2P path = J2 r197 字面)
trade-protocol-filter.js:925 hedge_placed event 后扩展:
- userKasia = JSON.parse(_hedgeGateOffer.meta).user_kasia_address (broker-intake-watcher 写 + broker-v3 同款)
- setImmediate fire-and-forget (不阻塞 _executeHedge return / state transition)
- 30s inline poll getCexOrder (3s 间隔, 复用 cex-bridge.js T2.3)
- filled: SUM(balance_change) 拿 cur balance → balance_after = cur + proceeds → INSERT user_ledger (asset='USDT', reason='hedge_filled:{cex_order_id}', ref_order_id=offerId) → recordChainEvent hedge_completed → enqueue dm_completion DM user
- timeout (30s 未 fill): recordChainEvent hedge_pending_fill, reconciler 5min cron retry post-fill (state 不阻塞)

DM 模板 (deterministic 跟 T1.5 chain-truth 同款):
"KAS 卖出成交 X KAS → Y USDT 入账\n账户余额: Z USDT (broker IOU)\n回 '余额' 查账户 / '提 N USDT TRC20' 提币"

## 进 T2.5c (Reading D step 4 — CEX fallback path)
broker-intake-watcher.js append:
- _scanUntakenOffersFallback() — 5min sub-tick 扫 broker maker 'open' offer with broadcast_at < now-30min AND taker IS NULL
- 对每个: broker auto-cancel 广播 cancel_v1 (chain TX 守 ch14 #44) → cex-bridge.placeCexOrder sell KAS → poll fill (复用 T2.5b helper) → user_ledger INSERT (reason='broker_fallback_fill:{offer_id}') → DM user
- 嵌进 startIntakeWatcher() 5min sub-tick (跟 _scanExpiredBrokerOffers + _scanStaleUnsolicited + _ensureBrokerUtxoSplit + _reconcileRefundsTick 同款 pattern)
~80 LOC

## framework regression cron 25/37
跟 5/7-5/9 baseline 一致 (24-27 PASS 浮动), 非 T2.5a 引入新 regression. 监测中.
