feat: [#24] improve E2E test feedback with verbose mode

- Use prove -v automatically for E2E tests to show real-time output
- Add timeout protection with configurable E2E_TIMEOUT environment variable
- Improve test messaging and progress notes

Users can now see exactly what's happening during VM provisioning.
