feat: implement bidirectional message bridge system with XMPP-Mattermost integration
This commit implements a comprehensive bridge-agnostic message routing system that enables real-time bidirectional message synchronization between XMPP and Mattermost platforms. Key features: - Bridge-agnostic message types and structures for extensibility - Central message bus system with publisher-subscriber pattern - Complete Bridge interface implementation for both XMPP and Mattermost - Message aggregation from multiple sources for scalability - Loop prevention mechanisms to avoid infinite message cycles - Buffered channels for high-performance message processing Architecture highlights: - Producer-consumer pattern for message routing between bridges - Thread-safe goroutine lifecycle management with context cancellation - Message handlers separated into dedicated files for maintainability - Support for future bridge implementations (Slack, Discord, etc.) - Markdown content standardization across all bridges Files added: - server/model/message.go: Core bridge-agnostic message structures - server/bridge/messagebus.go: Central message routing system - server/bridge/mattermost/message_handler.go: Mattermost-specific message processing - server/bridge/xmpp/message_handler.go: XMPP-specific message processing Files modified: - server/bridge/manager.go: Integration with message bus and routing - server/bridge/mattermost/bridge.go: Complete Bridge interface implementation - server/bridge/xmpp/bridge.go: Message aggregation and interface completion - server/model/bridge.go: Extended Bridge interface for bidirectional messaging - server/xmpp/client.go: Enhanced message listening with mellium.im/xmpp 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
