Cursor-style draft chats for DeepSeek Harness (DSH): New Session reuses the empty draft — and only mints a fresh one when every draft has unsent text — so empty placeholders never stack, exactly like Cursor's (or Telegram's) chat list.
Multi-agent orchestration and LLM model routing for DeepSeek Harness (DSH): semantic AI agent profiles, exact model routes, declarative teams and strategies, and bounded subagent delegation - a TypeScript plugin that adds no second runtime.
