//! # Application State Management
//!
//! This module provides comprehensive application state management for the Air
//! daemon, including configuration, service status, resource tracking, and
//! connection management.
//!
//! ## Architecture Overview
//!
//! The ApplicationState acts as the central coordination point for the Air
//! daemon, tracking all active connections, service states, requests, and
//! system resources. It follows the VSCode daemon state management pattern with
//! thread-safe, async-friendly data structures.
//!
//! ## Core Responsibilities
//!
//! 1. **Connection Management**
//!    - Track all connected clients (Mountain, Cocoon, Wind, etc.)
//!    - Heartbeat monitoring and validation
//!    - Connection pooling for Mountain clients
//!    - Graceful disconnection handling
//!    - Stale connection cleanup
//!
//! 2. **Service Status Tracking**
//!    - Monitor authentication service
//!    - Track update service state
//!    - Monitor indexing service
//!    - Track downloader service
//!    - gRPC service status
//!
//! 3. **Request Management**
//!    - Active request tracking
//!    - Request lifecycle management
//!    - Progress monitoring
//!    - Request cancellation support
//!
//! 4. **Resource Monitoring**
//!    - Memory usage tracking
//!    - CPU usage monitoring
//!    - Disk usage tracking
//!    - Network usage monitoring
//!    - Resource limit enforcement
//!
//! 5. **Performance Metrics**
//!    - Request count tracking
//!    - Success/failure rates
//!    - Average response time calculation
//!    - Uptime tracking
//!
//! ## Connection Types
//!
//! - **MountainMain**: Main editor process connection
//! - **MountainWorker**: Background worker processes
//! - **Cocoon**: Deployment and build system
//! - **Wind**: Communication layer
//! - **External**: Third-party integrations
//!
//! ## FUTURE Enhancements
//!
//! - [ ] Implement connection pooling for Mountain clients with load balancing
//! - [ ] Add connection encryption and authentication
//! - [ ] Implement connection rate limiting
//! - [ ] Add connection-based resource quotas
//! - [ ] Implement connection health checks with automatic recovery
//! - [ ] Add connection-based feature flags
//! - [ ] Implement connection audit logging
//! - [ ] Add connection-based request prioritization
//! - [ ] Implement connection state persistence across restarts
//! - [ ] Add distributed connection support for multi-node deployments
//! ## Thread Safety
//!
//! All state access is protected by async-friendly locks:
//! - `RwLock<T>` for read-heavy data (configuration, metrics, connections)
//! - `Mutex<T>` for write-heavy data (active requests, background tasks)
//!
//! This ensures concurrent access from multiple async tasks and threads
//! is safe and efficient.
//!
//! ## Performance Considerations
//!
//! - Use read locks where possible to allow concurrent access
//! - Minimize lock duration
//! - Use async-friendly lock types to avoid blocking runtime
//! - Consider lock-free alternatives for high-frequency updates
//!
//! ## Error Handling
//!
//! All methods return `Result<T>` with comprehensive error types:
//! - `Configuration`: Invalid configuration values
//! - `ResourceLimit`: Resource limits exceeded
//! - `Internal`: Internal state inconsistencies
