TypeScript interface-like schema validation system that's easier to use than Zod

/**
 * Main Schema factory - TypeScript-like schema validation
 *
 * Provides a clean, modular API for creating validation schemas without
 * mixing validation logic with schema definition logic.
 *
 * @example
 * ```typescript
 * import { Schema } from "fortify-schema";
 *
 * // Define a user schema
 * const UserSchema = Schema.object({
 *   id: Schema.number().int().positive(),
 *   email: Schema.string().email(),
 *   name: Schema.string().min(2).max(50),
 *   age: Schema.number().int().min(0).max(120).optional(),
 *   isActive: Schema.boolean().default(true),
 *   tags: Schema.array(Schema.string()).max(10).optional()
 * });
 *
 * // Validate data
 * const result = UserSchema.safeParse({
 *   id: 1,
 *   email: 'user@example.com',
 *   name: 'John Doe',
 *   isActive: true
 * });
 *
 * if (result.success) {
 *   console.log('Valid user:', result.data);
 * } else {
 *   console.log('Validation errors:', result.errors);
 * }
 * ```
