/**
 * after-pack.cjs
 *
 * electron-builder afterPack hook.
 *
 * Problem: electron-builder respects .gitignore when copying extraResources.
 * Since .gitignore contains "node_modules/", the openclaw bundle's
 * node_modules directory is silently skipped during the extraResources copy.
 *
 * Solution: This hook runs AFTER electron-builder finishes packing. It manually
 * copies build/openclaw/node_modules/ into the output resources directory,
 * bypassing electron-builder's glob filtering entirely.
