Module session_manager 

Session Manager for automatic PQXDH state synchronization

This module provides a state synchronization layer that:

• Uses a builder pattern for initialization and state loading
• Manages PQXDH protocol handlers and their state changes
• Automatically persists state changes to storage transparently
• Returns clones of specific types when requested
• Emits state change events for reactive programming

The SessionManager acts as a central hub for PQXDH state management, providing:

• Automatic Persistence: State changes are immediately persisted to storage
• Event Broadcasting: State changes are broadcast to subscribers
• Handler Management: Registration and lifecycle management of PQXDH handlers
• State Access: Fast access to current states via cloning

Usage Pattern

// Build the session manager (loads all states from storage)
let manager = SessionManager::builder(storage, messages_manager)
    .build()
    .await?;

// Register PQXDH handlers for automatic state listening
manager.register_pqxdh_handler("handler_1".to_string(), handler).await?;

// Get current state clones
let current_state = manager.get_pqxdh_state_clone("handler_1").await;

// Subscribe to state changes
let mut state_changes = manager.subscribe_to_state_changes();
