Deepseek Harness become great

Key features

• Give your DSH sessions better tools, durable workflows, and a cleaner path from idea to execution.
• PTY transport is used by default with a configured pipe fallback when PTY allocation is unavailable.
• Create durable, session-local recurring prompts that can be managed through agent tools, /loop commands, and the web UI.
• Exercise deterministic mock model turns through /mock run and /mock replay while preserving the real DSH AgentLoop, ToolRuntime, policy, and event flow.
• Loops resume with the session and keep each alarm independent from the others.
