广播逻辑重构: - AI 回复 (stream_start/response/stream_segments/multi_message/stream_end) 改用 broadcastToUser 发送给所有客户端 - 用户消息回显保持 broadcastToUserExcept 排除发送者 消息去重与角色修复: - CacheMessage(user) 移至回复生成后,避免本轮 LLM 调用出现重复用户消息 - action 角色消息在 DB 存储时映射为 assistant,DeepSeek 等模型不支持自定义角色 - stream_end defer 机制确保错误路径也会终止客户端思考指示器 OS 完整环境支持: - host 包重构为 HostBackend 接口 + Direct/WSL/Docker 三种后端 - 新增 os_exec/os_file/os_system 工具供 AI 在完整 Linux 环境中自由操作 其他: - 视觉模型注入 + 图片预处理后清空 Images 避免传给 Chat 模型 - 图片 URL 相对路径→绝对 URL 转换 - DevTools 链路追踪页面 + 重启修复 - 记忆搜索模糊匹配增强 - 后台思考定时调度支持 - 管理后台页面 (模型配置/用户管理等) - docs/api 更新广播机制说明 Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
