Subject: [PATCH] Fix Electron not opening: run npm install on core + check
 DISPLAY
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- core.sh: run npm install after cloning (downloads Electron binary
  into app/node_modules — required for the UI to launch)
- start.sh template: check if app/node_modules exists and run
  npm install on first start if missing
- start.sh template: warn if DISPLAY/WAYLAND_DISPLAY not set
