Description
### Summary
Pylint W0106 is triggered on each line of this code:
```py
[x + 1 for x in range(10)]
[1 for _ in range(2)]
[x in range(5) if x > 3 else 0 for x in range(10)]
```
But ruffs corresponding rule `B018` is not triggered on either.
### Version

Research direction
Reproduce the three list-comprehension examples with Ruff 0.11.13 and compare their behavior with Pylint W0106. Trace the implementation and tests for the corresponding B018 rule; done means each unused list comprehension is reported consistently with the intended rule behavior.
