对所有交易信号执行风控检查，将结果发布给交易员。

## When to Activate

- 收到研究员信号后自动触发
- 交易员执行前验证
- 用户问"这只票能买吗"
- 关键词：风控、仓位、回撤、止损

## Python Module

```python
from astock_trade.skills.risk_assessor import pre_trade_check, publish_decision

# 执行风控检查
account = {
    "total_assets": 1000000,
    "cash": 500000,
    "positions": {"600519": 100000},
    "daily_pnl": -5000,
}
decision = pre_trade_check(signal, account)
# Returns: {decision: APPROVED|REJECTED, checks: {...}, reason: "..."}

# 发布决策
publish_decision(decision)
```
