YAML 反斜杠修复扩大范围 — 之前只匹配 "D:\..." 格式，现在匹配所有双引号内含反斜杠的字符串。"outputs\session_20260420..." 会被正确转成 "outputs/session_20260420..."，不再导致 YAML 解析失败。这直接解决了第 10-19 轮的死循环。

_process_response 的 analysis_complete 检测已经在上一轮修好了，配合反斜杠修复，YAML 能正确解析出 action: "analysis_complete"，不会再 fallback 到代码执行。

文件选择改为只用最近一次上传的文件 — app.state.last_uploaded_files 记录上传的文件列表，/api/start 优先使用它，不再 glob("uploads/*.csv") 把所有历史文件都拿来分析。
