Research direction

Start with docs/benchmarking-workflow-dotnet-runtime.md and scripts/benchmarks_ci.py, then run the provided benchmark filter against the baseline and compare commits. Review the linked performance report and graphs for the two extracted-size regressions. Done means the regression is understood and the benchmark result no longer shows the reported increase.
