//! # Wind Advanced Synchronization - Real-time Document & UI Sync
//!
//! **File Responsibilities:**
//! This module implements advanced synchronization features that keep Wind's
//! frontend state in sync with Mountain's backend state in real-time. It
//! handles document changes, UI state updates, and broadcast updates across the
//! editor ecosystem.
//!
//! **Architectural Role in Wind-Mountain Connection:**
//!
//! The WindAdvancedSync module is responsible for:
//!
//! 1. **Document Synchronization:** Real-time tracking and synchronization of
//!    document changes between Wind (frontend editor) and Mountain (backend
//!    services)
//! 2. **UI State Sync:** Synchronizing UI state across multiple editor windows
//!    - Cursor positions
//!    - Selection ranges
//!    - Zoom levels
//!    - Theme and layout
//! 3. **Real-time Broadcasting:** Broadcasting updates to interested
//!    subscribers
//! 4. **Conflict Detection:** Identifying and handling conflicting changes
//! 5. **Performance Tracking:** Monitoring sync performance and health
//!
//! **Synchronization Architecture:**
//!
//! **Three Sync Layers:**
//!
//! **1. Document Synchronization (Every 5 seconds):**
//! ```text
//! Wind Editor (User Edits)
//!     |
//!     | Detect changes
//!     v
//! WindAdvancedSync
//!     |
//!     | Check for conflicts
//!     v
//! Mountain Services
//!     |
//!     | Apply changes
//!     v
//! File System / Storage
//! ```
//!
//! **2. UI State Synchronization (Every 1 second):**
//! ```text
//! Wind UI Window
//!     |
//!     | Capture state (cursor, selection, zoom)
//!     v
//! WindAdvancedSync
//!     |
//!     | Update internal state
//!     v
//! Apply to other windows
//! ```
//!
//! **3. Real-time Updates (Every 100ms):**
//! ```text
//! Subscribed Listeners
//!     ^
//!     | Broadcast updates
//!     |
//! WindAdvancedSync
//!     |
//!     | Queue updates
//!     v
//! Update Queue
//! ```
//!
//! **Document Synchronization States:**
//!
//! ```rust
//! enum SyncState {
//! 	Modified,   // Changed locally, not synced
//! 	Synced,     // Successfully synchronized
//! 	Conflicted, // Conflicts need resolution
//! 	Offline,    // Cannot sync (offline)
//! }
//! ```
//!
//! **Change Types Supported:**
//!
//! ```rust
//! enum ChangeType {
//! 	Update, // File content updated
//! 	Insert, // New file created
//! 	Delete, // File deleted
//! 	Move,   // File moved/renamed
//! 	Other,  // Other changes
//! }
//! ```
//!
//! **Conflict Detection (Microsoft-Inspired):**
//!
//! **Detection Criteria:**
//! - Document modified recently (within 10 seconds of last sync)
//! - Document is already in conflicted state
//! - Multiple simultaneous changes detected
//!
//! **Conflict Response:**
//! ```rust
//! return Err(format!(
//! 	"Conflict detected: Document {} was modified recently ({}s ago)",
//! 	document_id,
//! 	current_time - document.last_modified
//! ));
//! ```
//!
//! **Error Recovery (Circuit Breaker Pattern):**
//!
//! **Circuit Breaker States:**
//! 1. **Closed (Normal):** Operations proceed normally
//! 2. **Open (Degraded):** Too many failures, slow down sync interval
//! 3. **Half-Open (Testing):** Slowly testing if system recovered
//!
//! **Recovery Logic:**
//! - Track consecutive failures (max 3)
//! - On reaching limit: Increase sync interval to 30s
//! - On success: Reset interval to 5s
//! - Provides protection against cascading failures
//!
//! **Trackable Metrics:**
//!
//! **Sync.Status:**
//! ```rust
//! SyncStatus {
//! 	total_documents:u32,       // All tracked documents
//! 	synced_documents:u32,      // Successfully synced
//! 	conflicted_documents:u32,  // Have conflicts
//! 	offline_documents:u32,     // Cannot sync
//! 	last_sync_duration_ms:u64, // Time for last sync
//! }
//! ```
//!
//! **UI State Tracked:**
//!
//! ```rust
//! UIStateSynchronization {
//!     active_editor: Option<String>,
//!     cursor_positions: HashMap<String, (u32, u32)>,  // Document -> (line, col)
//!     selection_ranges: HashMap<String, (u32, u32)>,   // Document -> (start, end)
//!     view_state: ViewState {
//!         zoom_level: f32,
//!         sidebar_visible: bool,
//!         panel_visible: bool,
//!         status_bar_visible: bool,
//!     },
//!     theme: String,
//!     layout: LayoutState,
//! }
//! ```
//!
//! **Real-time Update System:**
//!
//! **Update Flow:**
//! 1. Queue updates as they occur
//! 2. Subscriber management per target
//! 3. Periodic broadcast (100ms)
//! 4. Emit events via Tauri
//!
//! **Subscription Model:**
//! ```rust
//! // Subscribe to updates for a target
//! sync.subscribe_to_updates("file-changes", "window-1").await?;
//!
//! // Queue updates
//! sync.queue_update(RealTimeUpdate { target:"file-changes".to_string(), data:modified_content })
//! 	.await?;
//!
//! // Broadcasts go to:
//! // - "real-time-update-window-1"
//! // - "real-time-update-window-2"
//! // etc...
//! ```
//!
//! **Tauri Commands:**
//!
//! - `mountain_add_document_for_sync` - Add document to sync tracking
//! - `mountain_get_sync_status` - Get current sync status
//! - `mountain_subscribe_to_updates` - Subscribe to real-time updates
//!
//! **Events Emitted:**
//!
//! - `mountain_sync_status_update` - Sync status changes
//! - `mountain_performance_update` - Performance metrics
//! - `real-time-update-{subscriber}` - Real-time updates
//!
//! **Initialization:**
//!
//! ```text
//! // In Mountain setup
//! let sync = Arc::new(WindAdvancedSync::new(runtime));
//! app_handle.manage(sync.clone());
//!
//! // Start sync tasks
//! let sync_clone = sync.clone();
//! tokio::spawn(async move {
//! sync_clone.start_synchronization().await;
//! });
//! ```
//!
//! **Usage Examples:**
//!
//! **Add Document for Sync:**
//! ```typescript
//! // From Wind TypeScript
//! await invoke('mountain_add_document_for_sync', {
//!     documentId: 'file-123',
//!     filePath: '/project/src/main.rs'
//! });
//! ```
//!
//! **Check Sync Status:**
//! ```typescript
//! const status = await invoke('mountain_get_sync_status');
//! console.log(`Synced: ${status.syncedDocuments}/${status.totalDocuments}`);
//! ```
//!
//! **Subscribe to Updates:**
//! ```typescript
//! await invoke('mountain_subscribe_to_updates', {
//!     target: 'file-changes',
//!     subscriber: 'my-window-id'
//! });
//!
//! // Listen for updates
//! app.handle.listen('real-time-update-my-window-id', (event) => {
//!     console.log('Real-time update:', event.payload);
//! });
//! ```
//!
//! **Performance Tracking:**
//!
//! **Metrics Collected:**
//! - Total messages sent/received
//! - Average latency
//! - Connection uptime
//! - Error count
//! - Sync duration
//!
//! **Logged on Every Operation:**
//! ```text
//! dev_log!("ipc",
//! "Document sync completed: {} success, {} errors, {:.2}ms",
//! success_count,
//! error_count,
//! sync_duration.as_millis()
//! );
//! ```
//!
//! **Integration with Other Modules:**
//!
//! **TauriIPCServer:**
//! - Used for broadcasting events to Wind
//! - Emits sync and performance updates
//!
//! **AdvancedFeatures:**
//! - Collaboration sessions work with document sync
//! - Shared focus on real-time updates
//!
//! **StatusReporter:**
//! - Sync status reported to Sky for monitoring
//! - Performance metrics shared
//!
//! **Future Enhancements:**
//!
//! - **Operational Transformation:** For collaborative editing
//! - **Conflict Resolution UI:** User-facing conflict resolution
//! - **Delta Sync:** Only sync changed portions
//! - **Sync Prioritization:** Prioritize active documents
//! - **Offline Sync Support:** Queue changes when offline
