Research direction

Start with the benchmark sources at src/benchmarks/real-world/bepuphysics2/SweepBenchmarks.cs, GroupedCollisionTesterBenchmarks.cs, and TwoBodyConstraintBenchmarks.cs, then run the supplied benchmarks_ci.py commands. Compare the reported Windows/x64 results with the baseline and inspect the linked test reports and diffs. Done means the regressions are explained and the benchmark results no longer show the reported issue.
