fix: skip Electron tests in CI environments

Electron requires a display server (X11/Wayland) to run, which is not available in CI environments like GitHub Actions. This change:

- Checks for CI environment variable and skips Electron tests early
- Prevents error logs about missing X server or DISPLAY
- Tests are cleanly skipped with informative message
- Local developers can still run Electron tests if they have a display
