feat(chat): Implement end-to-end encrypted swarm messaging system
- Add Swarm Chat documentation with architecture, API endpoints, and security considerations - Create database schema for chat conversations, messages, and typing indicators - Implement chat API endpoints for sending, receiving, and managing messages - Add client-side encryption utilities using RSA-OAEP with SHA-256 - Create chat page UI for viewing conversations and messages - Add chat type definitions for TypeScript support - Update database schema with new chat tables and relationships - Update sidebar navigation to include chat link - Enable true end-to-end encrypted messaging across swarm nodes without ActivityPub limitations
