Changed minimal default settings from executionOrder: 'v0' (legacy) to
executionOrder: 'v1' (modern default) when providing fallback settings.
This ensures workflows use the modern execution order by default, which
provides better performance and more predictable execution behavior.
Updated all affected tests to expect 'v1' instead of 'v0'.
