Research direction

Start with the linked performance report and compare the baseline and test commits for the Android HelloWorld Extracted Size benchmark. Follow docs/benchmarking-workflow-dotnet-runtime.md and run the provided benchmarks_ci.py command to reproduce the three Windows/arm64 regressions. Done means the regression is explained and the affected extracted-size results no longer regress.
