dsh-markdown-toc: Markdown Table of Contents Generation

The DeepSeek Harness plugin `dsh-markdown-toc` follows the "everything is a plugin" philosophy and is designed to generate Markdown table of contents locally. It is implemented entirely in Node and requires no external APIs, avoiding privacy leaks and network latency. It must be enabled in a configuration file after installation. It is suitable for privacy-sensitive or locally processing use cases, but please review the source code and license before installation.
