feat(ipc): add advanced IPC features for performance monitoring and collaboration

This commit introduces a comprehensive advanced features module for the Mountain-Wind IPC integration. The new `Source/IPC/AdvancedFeatures.rs` file adds sophisticated capabilities to enhance synchronization, performance monitoring, and real-time collaboration.

Key components implemented:
- Performance statistics tracking with metrics for message counts, processing times, error rates, and connection uptime
- Real-time collaboration session management with participant tracking and permission controls
- Intelligent message caching system with time-to-live (TTL) support for optimization
- Background monitoring tasks that run at regular intervals for performance stats, cache cleanup, and session management
- Tauri commands exposed for frontend integration (`mountain_get_performance_stats`, `mountain_create_collaboration_session`, etc.)
- Structured data models for performance stats, collaboration sessions, and cached messages

The implementation uses async Tokio tasks for background operations and leverages Arc/Mutex for thread-safe shared state. This enhancement builds upon the recent IPC documentation improvements and provides the foundation for advanced features like collaborative editing and performance analytics in the Mountain editor ecosystem.
