Research direction

Start with the reported baseline and compare commits, then follow the reproduction in performance/scripts/benchmarks_ci.py for the SOD - Android HelloWorld Extracted Size benchmark. Read docs/benchmarking-workflow-dotnet-runtime.md and the linked test report to compare the 2.66 MB baseline with the 2.67 MB result. Done means identifying and resolving the reported regression, with the benchmark no longer showing the size increase.
