DeepSeek Harness Plugin: Context Compression Fix for qwen3.8-27b

The DeepSeek Harness (DSH) plugin fixes an issue where the qwen3.8-27b model running on the NInfer engine exhausts its output tokens due to the default high reasoning level, causing context compression and title generation to be truncated. By disabling the thinking mode, applying recommended sampling parameters, increasing the output token limit, and constraining the reasoning intensity, the plugin ensures that the compression feature operates properly. After installation, restart the `dsh web` process and exactly match the model ID in the configuration file for the plugin to take effect.
