- Clean up kvstore constants file by removing unused functions and constants:
- Removed BuildXMPPUserKey, BuildMattermostUserKey, BuildGhostUserKey
- Removed BuildXMPPEventPostKey, BuildXMPPReactionKey functions
- Removed unused constants: KeyPrefixXMPPUser, KeyPrefixMattermostUser, etc.

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
