fix: resolve E2E workflow compilation and PATH issues

- Add missing 'dirs' dependency to Cargo.toml (used in e2e_tests.rs)
- Fix sudo PATH issue by preserving PATH environment variable
- Ensures cargo command is accessible when running with sudo privileges

This resolves the 'cargo: command not found' error in GitHub Actions.
