Research direction

Start with src/benchmarks/real-world/bepuphysics2/TwoBodyConstraintBenchmarks.cs, especially LinearAxisServo, and run the provided benchmarks_ci.py command with the DemoBenchmarks.TwoBodyConstraintBenchmarks filter. Compare the reported result with the linked baseline and test data; done means the improvement is reproduced and its cause or required follow-up is identified.
