Launcher build tool
install.ps1 downloads a portable Node.js 20 LTS into node/ and runs the
full build pipeline (npm install --ignore-scripts, Electron binary install,
electron-builder install-app-deps, npm run build, npm run pack).
Use this instead of a global Node install to avoid the ClangCL / Node version
issues documented in the repo root BUILD.md.
cd Tools\launcher
.\install.ps1
Output: dist\OctoLauncher.exe (portable) and dist\OctoLauncher_Installer.exe (NSIS).
The node/ directory is gitignored — it is recreated by install.ps1.
