kipina-codebench: itsenäinen benchmark-moduli git-submoduliksi

Refaktoroitu tests/-kansiosta omaksi moduliksi:
- prompts/ — kaikki promptit erillisinä .md-tiedostoina
- golden-examples/ — todo (taso 1) + blog (taso 2)
- benchmark.mjs lataa promptit ja esimerkit dynaamisesti
- Dockerfile.pytest, report-template.html, package.json, README.md
- results/ — tallennetut benchmark-tulokset
