v0.2.1

Fixed

• Corrected README quick-start wording so it no longer claims the default csharp example is the exact CI self-analysis command.
• Documented the stricter csharp,codesize,design ruleset combination used by CI self-analysis.

Verification

• scripts/dotnet.sh build -c Release
• scripts/dotnet.sh test
• scripts/dotnet.sh run --project src/MessSharp -- ./src text csharp --ignore-tests
• scripts/dotnet.sh run --project src/MessSharp -c Release --no-build -- ./src text csharp,codesize,design --ignore-tests
