sinohqb c7f1dca49d v0.3-s2: 3 个新规则 + 组合逻辑 + 33 个测试
## 新规则(共 6 种,增加 3 种)

### semantic_similarity
- 调用 OpenAI 兼容 embedding API(asyncio.gather 并发两路请求)
- 余弦相似度与 reference 比对,min_score 可配置(默认 0.7)
- API 异常时明确返回失败原因,不隐藏错误

### json_schema
- 验证回复是否为合法 JSON(支持 markdown 代码块剥离)
- required_keys / forbidden_keys / key_types 三维校验
- dot-path 支持嵌套字段("data.id")
- strict_json=false 模式非阻断校验

### safety
- 双层检测:关键词黑名单(零延迟)+ 可选 moderation API
- API 不可用时自动降级黑名单,不中止评测
- 支持自定义 flagged_categories

## 规则组合逻辑(rule_logic + rule_pass_threshold)

- models.py: EvalRuleConfig 增加 weight 字段;Case 增加 rule_logic / rule_pass_threshold
- models.py: 新增 RuleLogic 枚举(all / any / weighted)
- engine._save_rule_results: 按 rule_logic 决定 case 通过/失败
  - ALL:全部通过才通过(原有行为,向下兼容)
  - ANY:至少一条通过即通过
  - WEIGHTED:加权平均分 >= rule_pass_threshold

## 测试(43 → 76,新增 33)
- test_s2_rules_and_logic.py:3 个新规则的 pass/fail/边界/API 降级 + 5 个组合逻辑集成测试
