@deepseek-ai/dsh-tool-scout: DeepSeek Harness Environment Detection Plugin

`@deepseek-ai/dsh-tool-scout` is an environment probe plugin for DeepSeek Harness, designed to address the instability and inefficient tool usage caused by agents relying on environment judgment. This plugin provides an `environment_probe` tool that collects runtime environment, PATH commands, software versions, host resources (CPU/Memory/Disk), network ports, system services, and hardware information (e.g., GPU, USB) on-demand in read-only mode, outputting both normalized JSON and human-readable text. Its core advantage lies in avoiding model guessing and multiple slow command probes, supporting multi-dimensional scopes such as `environment`, `commands`, `software`, and `resources`, and featuring timeout control and concurrency limits.
