dsh-terse-mode: Terse Mode for Controlling Thinking, Search, and Subagents

`dsh-terse-mode` is a DeepSeek Harness plugin developed by `cspyz`, designed to resolve the slow responses and high token consumption caused by the DeepSeek model's unnecessary deep reasoning, frequent web searches, and sub-agent invocations through fine-grained control mechanisms. The plugin provides a four-level global intensity adjustment and independent toggles for thinking intensity, web search, and sub-agent control. Modifications can be applied instantly via the top of the chat page or the settings page, requiring no restart. Technically, it is built with pure JavaScript, features zero runtime dependencies, and includes local storage and configuration fallback mechanisms. Currently effective only for DeepSeek models, it allows users to optimize their interaction experience and inference costs through a simple UI.
