Removed three tests that exclusively tested negative conditioning/prompt
functionality which was removed in 2.5.0:
- test_refiner_v2_negative_advisor_repairs_negative_prompt_and_exports_one_string
- test_refiner_v2_returns_empty_negative_conditioning_when_negative_blank
- test_negative_prompt_repair_adds_poorly_rated_tags_persistently
Fixed six tests with stale assertions caused by API changes since they
were written: updated return-value unpack positions after negative output
was removed, dropped CONDITIONING-owned/CLIP-owned status checks that no
longer appear in any output, dropped Gemma3 tokenizer status check that
is only present in the error path now, updated Learning section header
name, and updated RETURN_NAMES assertion to check by value not position.
