Replace hardcoded validator class lists with a declarative #[Mixin] attribute and extract the mixin generation logic into a reusable CodeGen namespace under src-dev/CodeGen/. The new MixinGenerator discovers prefix definitions and filtering rules by scanning #[Mixin] attributes on the target namespace's classes, removing the need for hardcoded configuration. It supports configurable interface types (Builder for __callStatic, Chain for __call) with custom suffixes, return types, and root extends. This is the first step toward extracting the code generation into a standalone package that can map __call/__callStatic to any namespace, possibly for Respect/StringFormatter and any kind of project in the future.
