DSH Model Controller: Switch Models, Adjust Reasoning Intensity, Favorite Models, and Reorder Providers

The DeepSeek Harness plugin (DSH) adopts a plugin-based architecture and takes over the model slot to enhance model selection. Its core features include searching, filtering by provider, favoriting frequently used models, and adjusting thinking intensity. The thinking intensity level has per-model memory and automatically restores the corresponding level when switching models. For installation, download the `.tgz` file and install it via the host; the plugin will automatically take over the official selector. It supports integration with Magpie and has fallback interface configuration capability. Data is stored locally on the client; preferences are retained after uninstalling and reinstalling. It is compatible with DSH 0.1.7-rc.2 and Cordis 4.0.4.
