fix: 覆盖率统计全面修复 + 5漏洞修正
## 修复内容 ### C1: _mark_eval 反向操作符 (coverage.py) - EVALUATE 约束匹配支持 操作符 - WHEN OTHER 的自动检测（全部 WHEN 被否定时） ### C2: _mark_perform 反向操作符 (coverage.py) - PERFORM 同 _mark_if 的反向操作符匹配 - PERFORM UNTIL 条件截断后桥接器通过 branch_names 识别类型 ### H1: parse_single_condition 传递 fields (coverage.py) - collect_decision_points 调用时传 fields 参数 - NOT 前缀条件解析 (NOT WS-X > 50 → WS-X <= 50) ### H4: generate_data 输入约束 (__init__.py) - 文档注明接收原始源码，非预处理后文本 ### M1: not_map break (cond.py) - NOT 操作符映射循环添加 break ## 覆盖测试结果 - IF: 100% (T/F) - NOT IF: 100% (NOT_TRUE/NOT_FALSE) - PERFORM UNTIL: 100% (ENTER/SKIP) - EVALUATE: 100% (4 WHENs) - Nested IF: 100% (4 branches) - S15 回归: 17/17 PASS Co-Authored-By: Claude <noreply@anthropic.com>
