The workspace denies the default Clippy warnings, and the new tests tripped
three of them without changing what any of them proves:
- an expected value was built through `scale as f64` even though the tuple
already carries an `f64`, so the conversion is spelled in the literal and the
cast is gone;
- the standalone replay printed the executed plan and the per-partition counts
even though the surrounding assertions already require four nonempty
partitions, 24 rows in total and eight closing frames, so the diagnostics
are gone rather than exempted from the workspace lint.
No production code, assertion or fixture changes.
