Merge pull request 'fix: trigger.operator null + 覆盖反馈重试 - Closes #22, Closes #21' (#25) from dev/issue-22-fix-trigger-null into main

#22: _normalize_rule 补充 trigger 级别 operator (AND/OR) 默认值
#21: step1 验证失败时自动生成覆盖反馈并重试一轮
#22: step2 过滤空规则片段，避免污染下游

+**Issue 关闭规则**：
+- QE 测试通过 → 关闭 test-dev issue
+- QE 测试失败 + 发现新问题 → 开 dev issue (agent-task 标签)，**test-dev issue 保持 open**，评论 `阻塞: #<dev-issue>`
+- QE 测试失败 + dev issue 已存在 → test-dev issue **保持 open**，更新 dev issue
+- Dev issue 修复 + e2e 重新通过 → 关闭 test-dev issue
+- **绝不**在问题未修复时关闭 test-dev issue

+- Dev issue 被关闭但 QE 重验仍失败 → **重开 dev issue**，加 `## REOPEN 原因` 评论：
+  1. 已修复项（肯定进展）
+  2. 仍存在的问题（具体数据 + 阈值对比）
