Stage 4 (Harmonization) now uses two-tier approach:
- Score >= 0.92: auto-duplicate (embedding only, fast)
- Score 0.85-0.92: LLM verification via local qwen3.5 (think=false, ~3s)
- Score < 0.85: not a duplicate
This eliminates ~44% false positives from pure embedding similarity.
LLM_DEDUP_ENABLED env var controls the feature (default: true).
Also adds 10 applicability use case tests (bank+TAN, webshop+Stripe,
SaaS startup, energy provider, health app, automotive, law firm, etc.)
