Generate a Table of Contents (TOC) from Markdown headings.

Usage Scenarios

Scenario 1: Generate TOC for a README

User input: "帮我给这个README.md生成目录。"

Expected output: Run toc generator on README.md, output a bullet list of all headings from level 1 to 6 with proper hierarchical indentation, skipping headings inside code blocks.

Scenario 2: Filter by Heading Level

User input: "只需要二级和三级标题的目录。"

Expected output: Generate TOC filtered to include only heading levels 2 and 3, preserving hierarchy and indentation for the selected levels.

Scenario 3: Generate TOC with Anchor Links

User input: "生成带锚点链接的目录，方便跳转，不想要纯列表。"

Expected output: Generate linked TOC with markdown anchor references [Heading](#heading) for each entry, allowing quick navigation when used in markdown viewers that support anchor links.

Scenario 4: 给飞书文档生成目录

User input: "我在飞书上写了一篇项目的万字文档，想快速生成一个目录方便同事阅读，能不能帮我做？" Expected output: 根据markdown语法格式，提取文档中所有#标题，自动生成带锚点链接的目录（TOC）。由于飞书自带目录功能有层级限制，可以提供markdown格式的TOC供用户复制嵌入文档顶部。同时支持Github风格的[TOC]标签和Gitbook的{{summary}}格式。
