DeepSeek Harness Vision Bridge Plugin: analyze-image-tool

`analyze-image-tool` is a general-purpose visual interface plugin that provides a “visual bridging” layer for DeepSeek Harness text models. It supports any OpenAI-compatible endpoint, allowing multimodal models to analyze images through the `analyze_image` tool call. Core features include universal endpoint configuration, sandboxed secure reads, schema-safe compilation, automatic sanitization of API keys and reasoning traces, structured return payloads, and a WebUI settings panel. Installation requires Node.js ≥ 18.17 and DSH 0.1.x. Note that the image-pasting feature requires installing the `main` branch, and historical sessions cannot read previous attachments after a restart.
