dsh-claude-code-local: Invoking Local Claude Code in DeepSeek Harness

`dsh-claude-code-local` is a DeepSeek Harness plugin designed to register a local Claude Code CLI as an LLM provider, enabling key-free local execution. The plugin supports streaming JSON mode, is compatible with Claude Code's agent loop, tool calling, and permission management, and allows local models to be selected directly in the Harness interface. Installation requires DSH 0.1.0-rc.7 or later and a local CLI environment. The plugin offers flexible configuration and hot reloading, but is limited to macOS and Linux, and does not support cross-request context sharing or sampling parameter control in Harness.
