dsh-subagent-claude-live: Claude Code Streaming Subagent

The DeepSeek Harness (DSH) plugin `dsh-subagent-claude-live` addresses limitations such as the invisibility of the built-in subagent runtime and inflexible model configuration. It uses the `claude_code` and `claude_models` tools to turn Claude Code into a streamable subagent with real-time trajectory viewing. The plugin supports specifying the model, effort level, and permission mode at runtime, and can retrieve a real-time model list. Installation requires DSH version >= 0.1.1-rc.1 and a system-installed `claude` CLI (or a bundled payload). Configuration allows defining aliases to pin the model and effort level. The main limitations are that each run spawns a new process, history resumption is not supported, and deep mandatory execution is not provided.
