/**
* Class that provides the foundational structure for defining layered models, managing metadata,
* and exposing transpile method for all supported languages.
* It is intended to be extended by specific model implementations.
*
* @remarks
* - Children classes require the `@Domain` or other layer decorators to define the layer metadata.
* - It automatically collects properties of the model that are instances of `ZodType` and processes
* them into AST nodes.
*
* @example
* ```typescript
* @Domain({ name: 'User', file: 'user.ts' })
* class UserModel extends Zod2XModel {
* username = z.string();
* age = z.number();
* }
*
* const userModel = new UserModel({ modelName: 'User' });
* const userModelTypescript = userModel.transpile(Transpilers.Zod2Ts);
* ```
