dsh-kgraph-plugin: Project Knowledge Graph Visualization Plugin

dsh-kgraph-plugin is a read-only bundle plugin for DeepSeek Harness, designed to help developers quickly understand the architecture, dependencies, and layered design of complex projects by automatically generating module-level and file-level knowledge graphs. It supports multiple languages (Java, TypeScript, Python, Go, etc.) and multi-module recognition, providing a visual dashboard and the `project_kgraph` tool to help users refactor and optimize code more efficiently. After installation, users can simply input a project path to scan it and view the module dependency graph and file-level layered structure, without modifying the source code at any stage.
