Root cause: CEF views:// protocol can't serve ES modules.
Fix: navigate CEF to Vite dev server (http://localhost:9760/) via
ChromeDriver after launch. Graceful RPC degradation (no-ops when
RPC not initialized) allows app to mount without native bridge.

Results: 13 PASS, 5 FAIL (smoke, settings, theme, notifications,
diagnostics — selector differences, not infrastructure issues)
