DeepSeek Harness Plugin: dsh-plugin-novelai

`dsh-plugin-novelai` is a plugin for DeepSeek Harness that directly calls NovelAI V4.5 Full for image generation. It addresses the pain point of manually writing prompts by enabling automatic image generation from conversational descriptions, tag queries, and prompt inference. Users must configure a NovelAI token, which can be provided via chat, a configuration file, or environment variables. The plugin includes a built-in decoder for data processing, and the token is kept secure without being written to disk.
