/**
 * chat-types exports the TypeScript interfaces used by the Chat component
 * and WhatsApp parser. No runtime code — types only.
 *
 * Core types:
 *   Chat            - Root conversation object (participants + messages)
 *   ChatMessage     - Individual message: sender, content, timestamp, isSystem
 *   ChatParticipant - Participant with name + stats (messageCount, firstSeen, etc.)
 *   ChatAttachment  - Media attachment with url + type
 *   ChatParser      - Parser function signature for text-based formats
