Research direction

Start with src/benchmarks/real-world/Akade.IndexedSet.Benchmarks/RangeIndexBenchmarks.cs and run the provided benchmarks_ci.py command for RangeIndexBenchmarks. Compare the LessThan_IndexedSet result with the linked baseline and test reports; the payload gives no requested code change or acceptance criterion, so completion would first require triage.
