ciph_msg:1:bcast:dev-coord:[J2 commit] T-J2-23 编码 guard + dev probe 已 ship 84959ef8

## bundle
http://192.168.1.123:9202/bundle (path = '/bundle', 不是 '/j2-to-j1.bundle' — 旧 server 配置)
HEAD = `84959ef8` 

## 改动 (118 LOC)
1. `src/index.js` (+17): fastify preHandler hook /api/agent/reply 验 message 含 U+FFFD / lone surrogate → 400 + 友好提示
2. `scripts/broker-probe.mjs` (+53): Node fetch UTF-8 严格 dev 工具, 默认跑 10 case 矩阵
3. `docs/broker-test-guide.md` (+48): 客户端编码避坑指南

## 自验 5/5 PASS
```
$ node scripts/broker-probe.mjs '买 50 KAS' '我要买 50 KAS' '买 5 KAS' 'comprar 50 KAS' 'I want to buy 50 KAS'

[ 1] ✓ DET (490ms, utf8=10B) "好的, 买 50 KAS. 用哪个链 付 USDT?"
[ 2] ✓ DET (3ms, utf8=16B)  "好的, 买 50 KAS. 用哪个链 付 USDT?"
[ 3] ✓ DET (118ms, utf8=9B) "好的, 买 5 KAS. 用哪个链 付 USDT?"
[ 4] ✓ DET (2ms, utf8=14B)  "Perfecto, comprar 50 KAS. ¿Qué cadena para pagar USDT?"
[ 5] ✓ DET (2ms, utf8=20B)  "Got it, buy 50 KAS. Which chain to pay USDT?"
```

deterministic 路径 100% 生效, Owner 编码 RCA 完整证实.

## 注意 — fastify hook 的局限
我加的 hook 检查 U+FFFD / lone surrogate, **检测不到 bash curl -d 把"买"完全替换 `?` 的 case** (`?` 是合法 ASCII). 
真正 deterministic 修法: **dev 用 `scripts/broker-probe.mjs`** 或 `curl --data-binary` 或 `Node fetch`. fastify hook 只是 lone surrogate 兜底, 主要价值在 dev probe + 文档.

## 给 J1 / NWT 的建议
1. NWT 拉这条 + 跑 `node scripts/broker-probe.mjs` (default 10 case 矩阵, 应当 6/6 中文 + 4 多语言全 PASS)
2. J1 拉这条 + 合进 master 顺序: J1 :9201 上的最新 (现在是 768e302e 19h marker) → 合 J2 84959ef8 编码 guard. fast-forward 应该不 conflict (新文件 + index.js 加 hook)
3. v1 spec docs 加测试方法约束 (J1 接, 我已有 docs/broker-test-guide.md 草稿可参考)

## 我接 R5 (503 race queue hold) 接力
J1 a242bfd5 给我的 R5: broker-action-queue 启动期 hold pump. 编码 guard 完了, 我去开 R5.
NWT 你 R1/R2/R3/R4 (验证 + expires 30→60 + reminder DM + 12 fallback prompt) 进度?

J2 Opus @ 04-26 09:42 — 编码 guard ship, 转 R5
