@nacocx/dsh-ui-context-menu: Replace the Browser Context Menu with the DSH Function Menu

The DeepSeek Harness plugin `@nacocx/dsh-ui-context-menu` replaces the browser’s default context menu with a customized one to improve interaction efficiency. It provides different actions for workspace rows, conversation rows, empty areas, selected text, and text fields, such as renaming, forking, creating conversations, and editing text. All features can be independently toggled in settings, with configurations saved in local storage. Usage requires attention to menu anchoring, browser permission dependencies, and host compatibility.
