搜索接口：
- duckduckgo_search.py / ZhipuSearchAPI.py 切换到内网 searxng (原 43.251.225.121 / 134.122.191.214 已失效)
启动脚本清理：
- 删除废弃 backend/ 目录 (与 chat_web_backend/ 编译产物 jar MD5 相同，仅是改名副本)
- 删除 start_all.sh 与 langchain-chat/{start,stop,stop_quick,shutdown_all,restart}.sh (被 scripts/*-restart.sh 覆盖)
- 删除 chat_web_backend/{start,test_mysql}.sh
修复：
- scripts/backend-restart.sh 对齐当前实际在跑的 chat_web_backend.jar (profile=dev)
- scripts/log-trim-daemon.sh 把 LOCK 移到 /tmp 按用户命名，修复非首次用户跑时的 Permission denied
新增：
- scripts/start-all.sh：一键启动入口，串联 mysql/redis/milvus/langchain/backend/frontend，含端口自检
- chat_web_backend/application-local.yml.archived：原 backend/ 下 yj profile 覆盖配置的归档备份
其他：
- .gitignore 忽略 scripts/pptist-deploy/PPTist/ (323M 第三方源码树)
