dsh-bilingual-reader: A PDF Selection Translation Plugin for the DeepSeek Harness Sidebar

`dsh-bilingual-reader` is a sidebar plugin for DeepSeek Harness, designed to address frequent window switching and main conversation pollution when reading papers. It leverages the native PDF rendering engine to provide selected-text translation, multilingual mutual translation, and context-aware features. All translation calls are isolated from the main session and do not consume tokens. The plugin supports automatic clipboard monitoring for translation on desktop, requires a specific version of the DSH environment, and must be activated by restarting the application after installation.
