HTTP Request DSH Plugin: Using Native `http_request` Tool in DSH

`http-request-dsh-plugin` is a native plugin for DeepSeek Harness (DSH) designed to handle HTTP(S) request invocations using the built-in `http_request` tool, without relying on an MCP Server or external processes. The plugin supports various HTTP methods, proxy configuration, timeout control, and response truncation. It innovatively integrates a credential reference feature that utilizes Windows Credential Manager and Linux's `pass` to ensure sensitive information such as API Keys is not directly written into prompts or configuration files, instead limiting readable credential prefixes via a whitelist mechanism. Installation is flexible, supporting one-click installation from GitHub via the DSH CLI or cloning.
