What it may solve
DeepSeek Harness (dsh) bundle: headless one-shot session resume. `dsh --profile headless --resume <session-id> "task"` continues a persisted session (history and turn numbering carry on), prints and exits. Overrides the official headless runner via ctx.agents.resume(); install with `dsh plugin add github:EvieHe/dsh-resume-headless#v0.1.1`.
