dsh-dir-tree: DSH Web Session Floating Workspace Directory Tree

dsh-dir-tree is a floating directory tree plugin for the DeepSeek Harness (DSH) web client, designed to address the issue of errors associated with manual file path entry. The plugin displays the workspace directory of the current session in the bottom-right corner of the interface, supporting lazy loading of subdirectories, filename search and filtering, file type icon display, and directory highlighting. Users can click to select, double-click to copy the path, or directly drag files or folders into the chat interface to automatically fill in the full path. The directory tree automatically follows workspace or session changes, and its position is draggable. For installation, users must first prepare the DSH web environment, install the plugin via `dsh plugin add` from npm or a git repository (configuring build authorization is required for git installation), and finally start `dsh web` to use it.
