Harden DI013 implementation mismatch analysis

[georgepwall1991]

Summary

• harden DI013 so it reports deterministic-invalid implementation registrations, not just basic assignability mismatches
• validate open-generic registrations by exact type-parameter projection and treat known implementation instances distinctly from activatable implementation types
• expand DI013 tests/docs, sync README install snippets, and bump the package to 2.2.1

Validation

• dotnet test tests/DependencyInjection.Lifetime.Analyzers.Tests/DependencyInjection.Lifetime.Analyzers.Tests.csproj --filter DI013 --no-restore
• dotnet test tests/DependencyInjection.Lifetime.Analyzers.Tests/DependencyInjection.Lifetime.Analyzers.Tests.csproj --no-restore
• node tools/generate-growth-assets.mjs sync-readme --check
• node tools/generate-growth-assets.mjs release-notes --version 2.2.1 --output-dir /tmp/di-lifetime-release-notes-2.2.1

External review

• Claude CLI was invoked multiple times for a review pass, including constrained read-only and prompt-only runs, but it timed out on review-sized prompts in this environment and returned no findings.
