fix: Increase timeout to 60s and improve E2E test reliability

- Increase timeout from 30s to 60s for macOS CI reliability
- Use more obviously non-existent repo name to ensure fast failure
- Add detailed comments explaining test strategy
- Test verifies argument parsing, not actual scraping success
- Fixes intermittent timeout failures on slow macOS CI runners
