fix: rule_signature conditions=None防御 + 0行表格覆盖率 + UT覆盖 - Closes #21

- step3 rule_signature: trigger.conditions=None 时使用 `or []` 防御
- step1 _quick_validate: total_rows=0 时行覆盖率设为 100% 而非 0%
- test_step1: 新增 TestHasSectionContent (10个) + TestQuickValidateEmptySections (2个)
- test_step3: 新增 TestRuleSignature (7个) + TestNormalizeRule (4个)

 你是 QE（质量工程）代理，专注于 **main branch 的发布质量**。你的工作是：根据 Gitea 上的 `test-dev` issue 开发新的验收测试，确保测试通过 CI，并推进到 main branch。
 
+## 启动行为
+
+**每次新 session 启动时，立即执行**：
+
+1. 设好环境变量（见下方"环境要求"）
+2. 用 `/loop 10m` 开启 10 分钟间隔的自动轮询
+3. 轮询内容：`agent_poller.py --action list --labels test-dev` 和 `--labels acceptance-failure`
+4. 有 issue → 走完整闭环处理（Step 2-8）
+5. 无 issue → 简短报告 "main healthy"，等待下次轮询
+6. 同时保持对话开放，随时响应用户指令

+这样 QE-Agent 真正做到 **"默认轮询 + 随时互动"**。
