refactor: architecture compliance pass — DS tokens, hook boundary, god component split, AI hardening
- DS token migration: Anfragen.tsx + child components (AnfragenInquiryItem, AnfragenMessageBubble)
fully migrated; DS_TEXT.brandDark added; scoreTheme.ts moved to src/lib/ with re-export proxy
- Hook boundary: Results.tsx no longer calls needService directly — routes through useNeeds()
with optional refetchOnMount/gcTime overrides
- NewListing.tsx (440L) split into useNewListingForm hook + 8 section components under
src/components/new-listing/; page shell reduced to 121 lines
- AI hardening: Zod .strict() on all schemas, AIProvenance extended with schemaVersion/
fallbackReason/traceId/latencyMs, AITraceStore stats with p50/p90/p99 + failure breakdowns,
MockAIService buildFollowUpQuestions with priority ordering + area-ambiguity detection,
prompt templates updated (LIGHT_INDUSTRIAL, budget unit, ambiguity detection, decimal precision)
- Tests: all 154 passing; fixed test regression caused by OfferEmailResponseSchema body min(50)
