dsh-tool-autoexpand: Automatically expand new tool call cards in DSH

`dsh-tool-autoexpand` is a client-side plugin for the DSH browser, based on the MIT license, designed to optimize the viewing experience of tool invocation results. Its core function is to automatically expand the top-level folded rows of newly rendered tool invocation cards, while avoiding accidentally opening the row folding of internal blocks such as ReadBlock and TerminalBlock, thereby reducing manual operations. The plugin provides a default-enabled toggle switch card at the bottom of the sidebar, supporting adaptive light and dark themes. Users can instantly toggle the ON/OFF status by clicking the entire card without restarting the service. During installation, users can add the plugin via DSH commands from GitHub or npm. After installation, the DSH web interface must be restarted for the changes to take effect. To remove the plugin, execute the corresponding remove command and restart to completely disable it.
