A simple Gutenberg block that automatically generates a nested table of contents from post headings.

== Description ==

Add the **Table of Contents Block** anywhere in your Gutenberg editor. It scans H2–H6 headings in the post content and builds a nested, clickable table of contents. Links automatically work by adding IDs to headings.

No configuration needed. Works on single posts and pages (not archives or category listings).

* No theme editing required
You can activate the plugin on any site.
* Compatible with Gutenberg / Classic Editor
It processes the final rendered HTML.
* SEO-friendly
IDs are based on sanitize_title(), the same function WP uses for slugs.
* Works with headings that already have IDs
It does not overwrite existing IDs.

**Example:**
- Structure Your Content - Write your post or page using semantic headings (H2, H3, etc.)—just like you normally would.
- Insert the Table of Contents Block - Add the "Table of Contents Block" anywhere in your editor (e.g., right after the introduction).
- Let It Work Automatically - The plugin scans your headings, builds a hierarchical, scroll-linked table of contents in real time, and updates dynamically as you edit.
