Implement session replacement and WebSocket keepalive features

Browse Source 
Enhanced the session management by allowing a reconnect with the same username to replace the existing session, sending a logout message to the previous session. Introduced WebSocket keepalive functionality using Ping/Pong messages to detect stale connections. Updated documentation to reflect these changes and improve user experience during reconnections.
