 * Edge Bundle Script

 * Bundles the edge module for browser deployment using esbuild.
 * Produces both ESM and IIFE bundles with WASM support.

 * Usage:
 *   npm run build:edge

 *
 * Output:
 *   dist/edge/agentic-qe-edge.esm.js     - ESM bundle for modern bundlers
 *   dist/edge/agentic-qe-edge.iife.js    - IIFE bundle for direct browser usage
 *   dist/edge/agentic-qe-edge.esm.js.map - Source maps
