chore: diagnose 1M version data on production

POST /v1/canonical/generate/llm-dedup uses local Ollama (qwen3.5:35b-a3b)
to verify borderline duplicate matches (score 0.85-0.91). More accurate
than embedding similarity for compliance controls with subtle scope
differences (e.g. "documented" vs "implemented").
