Pull Request Overview

This PR implements validation to reject URI hosts that contain multiple port delimiters (multiple colons), which is invalid according to URI standards. The change ensures that hosts like "192.168.1.1:1111:2222" or "example.com:80:8080" are properly rejected during URI parsing.

• Adds validation logic to detect multiple port delimiters in host parsing
• Includes comprehensive test coverage for both invalid and valid cases
