test: add coverage for retryOrQuit and skipCloudInit auto-detection (#2810)

Both functions were added in recent commits but had zero test coverage:
- retryOrQuit (ed127cf): non-interactive mode now verified to throw
- skipCloudInit (2280550): 4 cases verify correct tier/cloud/mode conditions

1468 tests pass, 0 failures.
