Fix: launch Electron UI separately after A2A servers start

Browse source 
CS Core's start.js only starts A2A servers in electron mode — it does
NOT launch the Electron app itself (it says 'Electron app started
separately'). Switch to --ui-mode=headless for the background servers,
then explicitly launch electron from app/node_modules/.bin/electron.
Wait for registry /health before opening UI. Shut down servers when
Electron window is closed.
