dsh-ima-copilot: A DeepSeek Harness Plugin That Registers IMA Knowledge Base Q&A as the ima_ask Tool

`dsh-ima-copilot` is a native plugin for DeepSeek Harness (DSH) that integrates Tencent IMA Copilot's knowledge base Q&A capabilities into DSH Agents. By wrapping the `ima_ask` tool, it supports direct semantic retrieval, citation information return, and Web configuration management without additional processes or dependencies. It provides timeout management, concurrency limits, and secure credential handling, but carries API stability risks and does not retain conversation history. Installation requires adding the plugin via the CLI and restarting the Agent, after which the Agent can directly invoke the tool to obtain a JSON-formatted response containing the answer and citations.
