test: 移除硬编码路径，适配新 config.py 目录结构 - Closes #10

- conftest.py: secrets 路径改为多位置查找 (QE_SECRETS_PATH env → ~/.openclaw/config/ → workspace-document-analyzer/config/)
- conftest.py: IR 默认路径改为 output/final/ir_final.json (匹配 config.IR_FINAL_JSON)
- conftest.py: parsed 默认路径改为项目相对路径
- agent_poller.py: 添加 --labels 过滤 (向后兼容)
- 新增 agents/QE_AGENT.md + scripts/start_qe_agent.sh

scripts/agent_poller.py
