nyzeep/dsh-thinking-level: DeepSeek Harness Thinking Level Selector

The DSH `dsh-thinking-level` plugin aims to address the efficiency issue of filtering model thinking levels in the DeepSeek Harness Web UI. It displays only the levels supported by the current model declaration and selects the highest level by default, thereby optimizing the user interface. Users must enable it manually via the source code and should carefully verify source code security during installation.
