/*
* This script adds a floating navigation button to Google AI Studio that displays
* a table of contents for all chat messages in the conversation.
*
* Features:
* - Shows both user messages and AI responses in chronological order
* - Each item is numbered sequentially from top to bottom
* - Displays file attachments along with regular chat messages
* - Detects and lists code blocks as sub-items under their parent messages
* - Clicking an item scrolls to that message and highlights it
* - Supports both light and dark themes
