Pull Request Overview

This PR adds support for resolving additional type arguments for CustomHandler methods when they have multiple generic type parameters. The enhancement allows CustomHandler methods to automatically receive type arguments from the matched AssignableTo type, enabling more sophisticated scenarios like Entity Framework's IEntityTypeConfiguration pattern.

Key changes:

• Enhanced CustomHandlerModel to support multiple type arguments instead of a single type name
• Added validation for CustomHandler methods with multiple generic parameters
• Modified source generation to properly format multiple generic arguments in method invocations
