* Add test coverage for with_golden_first scope
Test verifies that the with_golden_first scope correctly orders
golden cards before non-golden cards in query results.
* Refactor golden test: use instance variables, add subordering coverage
Extract @golden and @non_golden fixtures into setup for reuse across
all tests. Simplify with_golden_first test to verify both primary
ordering (golden before non-golden) and subordering preservation.
