本次更新完善了「系统设置 → 日志审计」：平台操作统一入库（含各入口创建对话），支持筛选、分页、JSON/CSV 导出；删除类或关联资源已不存在的记录不再提供「打开关联资源」，并修复 chat 跳转按钮的脚本错误。审计保留 retention_days（0 为不清理），进程启动时清理一次，运行中改为每小时检查并删除超期 audit_logs；不再记录对话正文与终端/WebShell 每条命令。
This release improves System Settings → Log Audit: platform actions are recorded consistently (including conversation creation from all entry points), with filtering, pagination, and JSON/CSV export. The “open related resource” action is hidden when the resource was deleted or is gone, and the chat jump button script error is fixed. Retention uses retention_days (0 = no purge): one cleanup at startup, then hourly while the process runs. Chat content and per-command terminal/WebShell logs are not audited.
