dsh-thinking-summary: DeepSeek Harness Reasoning Flow Segmented Summary Plugin

`dsh-thinking-summary` is a DeepSeek Harness plugin designed to convert a model's long reasoning chain into a readable summary. It uses a remote service to break down and summarize the reasoning stream, providing three display modes: collapsed summary, expanded summary chain, and raw text. Users can configure the summarization model in settings. The plugin supports lightweight Markdown rendering and groups paragraphs by approximately 160 characters to avoid redundancy. It balances interface cleanliness with reasoning detail, making it suitable for developers who need to inspect detailed thinking processes while maintaining a clear interface.
