It looks like optionInterface or commonInterface since it is a common interface for the package types.

Please, add a short-comment description to the type: why do we need the interface? Since it is not obvious for a code reader.

Pull Request Overview

This PR implements a new generic Generic[T] type for safe optional value handling in Go, providing type-safe alternatives to nil pointers and sentinel values. The implementation includes comprehensive MessagePack serialization support and maintains compatibility with existing generated types.

• Introduces Generic[T] type with standard optional methods (Some, None, IsSome, Get, etc.)
• Adds interface compliance assertions to ensure all generated types implement the common interface
• Updates documentation and golangci-lint configuration for better test handling
