dsh-fetch-models-unselect-all: One-Click Clear Model Selection List

This plugin is designed for DeepSeek Harness to address the cumbersome process of bulk-resetting selections in the “Fetch Available Models” dialog. It adds a “Deselect All” button to the action bar at the bottom of the dialog, allowing users to clear all selected models with a single click. It uses DOM listeners and React state synchronization to ensure that actions remain consistent with the UI state. The tool runs entirely on the client side with no side effects; users can install it via a command and use it after restarting the service. It is well suited for scenarios requiring frequent resets of the model list.
