fix: improve connection reliability with better handshake detection

[ThomasK33]

Improve Claude connection reliability and queue processing

This PR enhances the connection handling and queue processing for Claude Code:

• Increases the connection wait delay from 200ms to 600ms to ensure Claude is fully ready before sending queued mentions
• Implements a more robust connection check that verifies WebSocket handshake completion
• Adds progressive polling after connection to ensure handshake is complete
• Increases the delay between sequential message sends to 25ms (from 10ms) to prevent overwhelming the WebSocket connection
• Adds more detailed logging for connection and queue processing states
• Implements a retry mechanism that polls until handshake completes when triggered by a new connection

These changes should significantly improve reliability when sending multiple mentions to Claude, especially immediately after connection.
