+/*
+Package lazyconn provides mechanisms for managing lazy connections, which activate on demand to optimize resource usage and establish connections efficiently.
+
+## Overview
+
+The package includes a `Manager` component responsible for:
+- Managing lazy connections activated on-demand
+- Managing inactivity monitors for lazy connections (based on peer disconnection events)
+- Maintaining a list of excluded peers that should always have permanent connections
+- Handling remote peer connection initiatives based on peer signaling
+
+## Thread-Safe Operations
+
+The `Manager` ensures thread safety across multiple operations, categorized by caller:
+
+- **Engine (single goroutine)**:
+  - `AddPeer`: Adds a peer to the connection manager.
+  - `RemovePeer`: Removes a peer from the connection manager.
+  - `ActivatePeer`: Activates a lazy connection for a peer. This come from Signal client
+  - `ExcludePeer`: Marks peers for a permanent connection. Like router peers and other peers that should always have a connection.
+
+- **Connection Dispatcher (any peer routine)**:
+  - `onPeerConnected`: Suspend the inactivity monitor for an active peer connection.
+  - `onPeerDisconnected`: Starts the inactivity monitor for a disconnected peer.
+
+- **Activity Manager**:
+  - `onPeerActivity`: Run peer.Open(context).
+
+- **Inactivity Monitor**:
+  - `onPeerInactivityTimedOut`: Close peer connection and restart activity monitor.
