Kör Claude som AI-modell i Guidad Felsökning

- AI-motor (ai.ts): Claude Opus 5 via officiella TypeScript-SDK:n.
  Teknikerns bekräftade dokumentation skickas med ärendebriefen som
  kontext; svaret är schema-bundet (structured outputs) och strikt
  klassificerat enligt AI-reglerna: observation, verifierat, hypotes
  (kräver alltid verifiering) och rekommendation, plus ETT konkret
  nästa steg. Fryst systemprompt med promptcache; automatisk
  server-side fallback till Anthropics rekommenderade reservmodell
  när säkerhetsklassificerarna avböjer; refusal hanteras innan
  innehållet läses.
- Onboarding enligt direktivet: organisationens Claude API-nyckel
  läggs in på startsidan (maskerat fält). Utan nyckel guidar den
  deterministiska metodiken ensam. MVP-varning: nyckeln lagras på
  enheten och anropet görs från webbläsaren — i produktion via
  backend.
- AI-svaren loggas som händelser med modellnamn och visas i guiden;
  de är arbetsmaterial och filtreras ur kundrapport, Live Share och
  databasens delningsfunktion, precis som hypoteser.
- Master Prompt uppdaterad: AI-wrapper ovanpå Claude API, standard-
  modell claude-opus-5.

Verifierat: 25 vitest-tester gröna (inkl. promptbygge, svarstolkning
och systemprompt-regler), produktionsbygge ok, Playwright-röktest
genom hela flödet.
