/**
 * A decorator function to create a layered model by extending a class with additional metadata.
 * This decorator ensures that each class instance is a singleton and associates metadata with
 * transpilerable properties of the class.
 *
 * @param opt - The metadata options for the layer, of type `IZod2xLayerMetadata`.
 *
 * @returns A class decorator that extends the target class with the following features:
 * - Singleton instance management.
 * - Automatic assignment of metadata (`IZod2xMetadata`) to transpilerable properties.
 * - Layer-specific metadata association for Zod types.
 *
 * ### Usage
 * Apply this decorator to a class to enable layered modeling and metadata management.
 *
 * ### Example
 * ```typescript
 * @Layer({ name: "User", file: "user.ts", index: 0 })
 * class ExampleClass {
 *   // Class implementation
 * }
 * ```
 *
 * ### Usage
 * It can also be used to create custom layers like Domain, Application or Infrastructure:
 * ```typescript
 * function Domain(opt: Pick<IZod2xLayerMetadata, "file" | "name">) {
 *   return Layer({ ...opt, index: EZod2XLayer.DOMAIN });
 * }
 *
 * @Domain({ name: "User", file: "user.ts" })
 * class User {
 *  // Class implementation
 * }
 * ```
