new-project-init: Question-Driven Initialization of Project Documentation and Collaboration Standards

`new-project-init` is a workflow plugin for DeepSeek Harness (DSH), designed to codify documentation standards and AI collaboration workflows through Q&A flows. It supports cross-platform use and focuses on refining existing projects, helping organize existing codebases or initialize new ones by generating specification files such as CLAUDE.md/AGENTS.md, with 31 built-in templates. The plugin does not automatically refactor code; it only handles documentation and organization, and can be invoked via commands or natural-language instructions.
