/**
 * Build CodeForge Windows installer (Inno Setup) from the portable app folder.
 *
 * Prerequisites:
 *   - Portable build at ../VSCode-win32-x64/CodeForge.exe
 *     (npm run vscode:package:win:portable  OR full vscode:package:win)
 *   - Inno Setup 6+ (ISCC.exe) — installs via winget if missing:
 *     winget install JRSoftware.InnoSetup
 *
 * Usage:
 *   node scripts/build-installer-windows.mjs
 *   node scripts/build-installer-windows.mjs --source path/to/VSCode-win32-x64
