Matches commit 8d0a959 model flip — extractor default is now
ModelID.qwen36 ("qwen3.6:latest"). The previous test name + assertion
were stale and failed on `swift test --package-path packages/Memory`
with the "Optional(qwen3.6:latest)) is not equal to (qwen2.5-coder…)"
diff. No production code change.
