Research direction

Start with src/benchmarks/real-world/bepuphysics2/TwoBodyConstraintBenchmarks.cs at the three linked benchmark ranges, then run the provided benchmarks_ci.py command. Compare the BallSocket, AngularServo, and LinearAxisServo results with the linked baseline and test reports. Done means determining whether the reported improvements are expected and recording the appropriate follow-up.
