dsh-multi-root-explorer

`dsh-multi-root-explorer` is a DeepSeek Harness plugin designed to replace the native base view and provide developers with efficient multi-directory workspace management. Through a dual-tab layout (conversation tree on the left, resource tree on the right), it implements fixed multi-root workspaces, on-demand file loading, and real-time disk change awareness. It supports file drag-and-drop references, custom `@` menu overrides, session directory operations, and native archiving. Installation requires DSH version >= 0.2.0-rc1 with Popover API support, and the app must be restarted after installation.
