/**
 * Creates a Zod schema for a given class constructor.
 *
 * Scans the class for property decorators and applies their validation rules
 * to the generated schema.
 *
 * @param target - The class constructor to generate the schema for
 * @returns A cached Zod object schema with all validations applied
 *
 * @example
 * ```ts
 * @schema({ description: 'User data' })
 * class User {
 *   @property({ description: 'User email' })
 *   @validate('email')
 *   email: string;
 *
 *   @optional()
 *   @validate('min', 3)
 *   name?: string;
 * }
 *
 * const userSchema = toZodSchema(User);
 * ``` *
 * @features
 * - Schema-level descriptions via `@schema` decorator
 * - Property-level descriptions via `@property` decorator
 * - Optional properties via `@optional` decorator
 * - Built-in validations (min, max, pattern, etc.)
 * - Custom validation rules via `@validate` decorator
 * - Automatic schema caching for performance
