yuioi666/dsh-plugin-model-capability: DeepSeek Harness Model Capability Management

The DeepSeek Harness (DSH) plugin aims to simplify model capability configuration through a visual interface, addressing the time-consuming and error-prone process of manually editing `llm-pi-ai.providers`. Its core features include managing thinking levels, context windows, gateway compatibility (such as Reasoning Effort), and routing defaults, as well as supporting directory synchronization from models.dev, one-click presets, and diagnostic checks. Users can load directories, apply presets, edit parameters, and save configurations. Note that custom presets fully replace user configurations, and empty non-off thinking levels are blocked. This plugin provides developers with a practical toolkit for fine-grained control over model behavior.
