Merge pull request 'fix: [P0] IR 结构化覆盖率不足 (36.1% < 70%) - Closes #21' (#24) from dev/issue-22-fix-trigger-null into main

- 新增章节覆盖率检查（functional sections vs covered sections）
- 新增表格行覆盖率检查
- 不达标时输出未覆盖章节列表
- passed 条件增加覆盖率阈值判断

 测试必须全部通过（至少 Layer A 和 Layer B），才能提交。
 
+**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
+
+**Issue 重开规则**：
+- 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）
+  3. 结论：为什么修复不完整
+- 重开后同步更新关联 test-dev issue
