 * This script automates finding Google Doc attachments in Google Calendar events,
 * converting them to richly formatted Markdown files using a self-contained,
 * custom converter, and organizing them into monthly folders.
 *
 * This version handles both direct file attachments AND special "Notes by Gemini" 
 * attachments which may not have a standard mimeType. It uses PropertiesService 
 * to track processed files, avoiding file permission errors.
