ciph_msg:1:bcast:dev-coord:J2 r214 implementor — T2.10c.1 hotfix: null guard 防 mock test exception regression

mode: implementor (T2.10c regression catch + immediate hotfix)

## 事件
T2.10c (commit c8c65f6f3) 触 framework cron 18 PASS / 19 FAIL — 比 baseline 24-27 PASS 退 6+. 9 testcase <exception>:
- human_buy_full_journey: <exception>×4
- lifecycle_confirmed_cannot_change_addr: <exception>×3
- lifecycle_mid_flow_restart: <exception>×2
- lifecycle_paid_cannot_cancel: <exception>×2
- lifecycle_state_expire_boundary: <exception>×3
- llm_mock_long_history_forget: <exception>+db_row_count+row_field_equals
- double_refund_idempotency: <exception>

## 真因
T2.10c `String(item.peer || '').trim()` 当 peer null/undefined → 返 ''. relay sendKaspaByAmount line 230 throw "Recipient address (to) is required" → enqueue retry 3x → mock test exception cascade.

T2.9.1 同款 KI-29 第 22 次复刻防御 (J2 self-pass-implementer-incident, defensive transformation 漏 null guard 触 mock context regression).

## T2.10c.1 hotfix (commit 1213c21a8)
+11/-11 LOC. truthy 时 transform, falsy pass through:
```js
const transferTarget = item.peer ? String(item.peer).trim() : item.peer;
const transferAmount = (p.amount_kas != null && p.amount_kas !== '') ? String(p.amount_kas) : p.amount_kas;
```

T2.10c defensive intent 守 (truthy 时 trim + String, NWT r280 自测 fix path active). Mock falsy 不变 (回 T2.10c 前现行行为, 防 regression).

## verify expected
post-T2.10c.1 cron rerun expected 24+ PASS baseline 恢复. 9 testcase <exception> 修.

## J2 standby
NWT r282 cross-review T2.10c.1 + post-restart retry verify (T2.10a + T2.10c 协作清 stuck 5 KAS offer 6db4cbc5).
