3-336: Consider adding a compact table of contents for scanability.

Great coverage, but this file is very dense. A short in-file TOC (Quick Start, APIs, Realtime, Pitfalls, Examples) would make it easier to navigate while keeping the same content.

As per coding guidelines, "Use clear and concise language in all documentation and .cursorrules files" and "focus on practical use cases for Cursor AI users."
