Pull Request Overview

This pull request enhances the set_constant method to improve its API design and error handling. The main purpose is to make set_constant return the instance being registered and add validation when using type aliases.

• Modified set_constant to return the registered instance instead of self for better method chaining
• Added validation to raise ValueError when alias=True but no on parameter is provided
• Updated documentation to demonstrate the improved API usage
