🤖 fix: Update E2E test dist paths and Storybook CSS import

- Update REQUIRED_DIST_FILES in E2E tests to check for:
  - dist/cli/index.js (CLI entry point)
  - dist/desktop/main.js (Electron main process)
  - dist/preload.js (unchanged)
- Fix Storybook preview CSS import: src/styles/globals.css → src/browser/styles/globals.css

Fixes E2E test error: Missing build artifact at dist/main.js
Fixes Storybook build error: Could not resolve ../src/styles/globals.css
