Measures fit() and transform() wall-clock time for 40 representative transformers across all modules, on synthetic data of configurable size. Supports saving a baseline and comparing later runs against it, failing when a benchmark regresses beyond a threshold. Not collected by pytest and not run in CI; see benchmarks/README.md. Baseline recorded before the 2.0 refactoring (polars support, numpy compute) as the reference to verify that the refactoring speeds up the transformers rather than slowing them down. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Rebase the branch onto main (which now includes the ArbitraryImputer, MissingIndicator, MeanImputer, CountEncoder, Winsoriser and MeanNormalisationScaler renames) and update run_benchmarks.py and the recorded baseline to reference the new names instead of the deprecated aliases. Only the benchmark's case labels and imports change; the recorded timing values in the baseline JSON are untouched, so --compare keeps matching every case against the pre-2.0 baseline instead of reporting the renamed ones as "not in baseline".
