test: Test-Suite für Single-Server-Konfig, Loop-Logik und Skripte

Node-eigener Test-Runner (keine Dependencies). 35 Tests:
- pure-logic: parseVerdict/parseBlockers/normalizeForComparison (real aus
  der Extension extrahiert), inkl. PASS-WITH-CONCERNS-Abgrenzung
- config: models.json/settings.json-Invarianten (kein Port 8002, nur
  llama-cpp-single/qwen3.5-single), Querkonsistenz
- extension-guards: Regression-Schutz fuer jeden Fix (select positional,
  kein switchModel, before_agent_start-Hook, passed-Logik, Loop-Fallback)
- scripts: bash -n + Single-Server-Invarianten

Start: ./run-tests.sh
