Enhancement: Add granular connection state events

[akberc]

Summary

Add more granular connection state events to help applications track connection lifecycle.

Motivation

Currently, the client emits \�rror\ and \close\ events. More granular events would help applications provide better user feedback and handle connection states appropriately.

Proposed Events

• \connecting\ - Connection attempt started
• \�uthenticating\ - Authentication in progress
• 
  eady\ - Fully connected and authenticated
• 
  econnecting\ - Attempting to reconnect after failure
• \disconnecting\ - Graceful disconnect in progress

Example Usage

\\ ypescript
client.on('connecting', () => console.log('Connecting...'));
client.on('authenticating', () => console.log('Authenticating...'));
client.on('ready', () => console.log('Ready!'));
client.on('reconnecting', (attempt) => console.log(\Reconnecting (attempt )...));
\\

Benefits

• Better UX with connection status feedback
• Easier debugging of connection issues
• Support for connection state UI indicators
