One chat for everything in DeepSeek Harness (DSH): no more hunting for old conversations. Each message goes to the topic it belongs to, with its own context.

Branch from any answer and keep branching at any depth. Recursively isolated follow-ups that leave the main DSH task untouched.

会话管理菜单、归档管理、轮次级删除、重新生成、记忆管理、任务管理、话题导航。Conversation management menu, archive management, round-level deletion, regeneration, memory management, task management, topic navigation.
