dotnet-test: polyglot description + keywords (mirror 0.2.0)

[0101]

Reframes the dotnet-test external catalog entry to reflect the plugin's polyglot test-generation pipeline (11 languages: .NET/C#, Python, TypeScript/JavaScript, Java, Go, Ruby, Rust, C++, Kotlin, Swift, PowerShell) and adds polyglot keywords so non-.NET developers can discover it. Mirrors the dotnet/skills 0.2.0 bump (dotnet/skills#852). source stays unpinned (tracks main), so no behavior change. Edited the source plugins/external.json; .github/plugin/marketplace.json regenerated via npm run build.

Description

The dotnet-test marketplace entry read as ".NET-only", but the plugin ships a multi-agent (Research → Plan → Implement) test-generation pipeline with per-language guidance for 11 languages. Developers in Python, TypeScript, Java, Go, Rust, etc. couldn't find it via marketplace search.

• Description reframed to lead with polyglot test generation, keeping the .NET-focused analysis (coverage/CRAP, testability, platform detection, MSTest/xUnit migration).
• Keywords add polyglot terms (polyglot, test-generation, unit-tests, python, typescript, java, go, rust) alongside dotnet/testing, within the 10-keyword limit.
• Version mirrored to 0.2.0 to match the plugin manifest (Bump dotnet-test to 0.2.0 dotnet/skills#852, merged).

Edited in the source plugins/external.json; .github/plugin/marketplace.json regenerated via npm run build. npm run plugin:validate passes.

Type of Contribution

Additional Notes

• source stays unpinned (tracks dotnet/skills main) — discoverability/metadata only, no behavior change.
• Complements Enable VS Code subagent fan-out for the dotnet-test code-testing agents dotnet/skills#847, which enabled VS Code subagent fan-out for these code-testing-* agents.
• Keyword set is capped at 10 by the catalog validator; the full 11-language list lives in the description.
