/****
 * Module Fetcher
 *
 * Fetches and caches ESM modules for MDX rendering.
 * Handles direct file reads, HTTP fallback, and recursive dependency resolution.
 *
 * Features:
 * - Distributed transform cache for cross-pod sharing (Redis/API)
 * - Local filesystem cache for fast repeated access
 * - Parallel nested import resolution
