Pull Request Overview

This PR adds support for IPv6 URLs in AMQP connections by properly parsing IPv6 addresses in bracket notation (e.g., amqp://[::1]). The change ensures that IPv6 addresses wrapped in square brackets are correctly processed when establishing connections.

• Strips square brackets from IPv6 addresses in URLs before passing to socket connection
• Adds test coverage for IPv6 URL connection functionality
