/**
 * Component Normalizer - Transforms JSON components where business logic requires it
 *
 * This module ONLY handles transformations that are actually necessary:
 * 1. Columns shorthand notation (columns: 3 → array format)
 * 2. Recursive processing of nested components
 * 3. Gap application for columns
 *
 * All other properties are preserved as-is from TypeBox validation.
 * This prevents information loss and maintains single source of truth.
