Node.js implementation of LegalMarkdown for processing legal documents with markdown and YAML - Complete feature parity with Ruby version

/**
 * Template Loop Processing Extension for Legal Markdown
 *
 * This extension adds support for template loops and conditional blocks using
 * the {{#variable}}...{{/variable}} syntax. It enables iteration over arrays
 * and conditional rendering of template sections.
 *
 * Features:
 * - Array iteration: {{#items}}...{{/items}}
 * - Conditional blocks: {{#loyaltyMember}}...{{/loyaltyMember}}
 * - Nested loops support
 * - Context management for loop variables
 * - Integration with field tracking
 *
 * @example
 * ```typescript
 * import { processTemplateLoops } from './template-loops';
 *
 * const content = `
 * {{#items}}
 * - {{name}} {{onSale ? "(ON SALE!)" : ""}} - ${{price}}
 * {{/items}}
 * `;
 *
 * const metadata = {
 *   items: [
 *     { name: "Product A", price: 10.99, onSale: true },
 *     { name: "Product B", price: 15.50, onSale: false }
 *   ]
 * };
 *
 * const result = processTemplateLoops(content, metadata);
 * ```
