Add Secure Automatic Authorization for DeepSeek Harness with dsh-auto-mode

### 正式翻译版本（符合技术文档译法）： dsh-auto-mode is a DeepSeek Harness workflow plugin maintained by NanmiCoder, which inserts an Auto permission tier between Workspace Write and Full access. Daily operations run through the official workspace-write sandbox, with semantic risks classified by the current Session model, and critical path damages will be rejected before execution. This article covers the directory page, GitHub and npm verification of installation commands, decision rules, and security boundaries.
