After deploying v5 analysis.py, run this once to overwrite v4 scores in
the DB with v5's interpretation. Idempotent — skips rows already at v5.
Has --dry-run mode to preview the change without AI calls or DB writes.
Live mode prompts for confirmation (skipped if stdin is non-tty so it
also works under `docker exec`).
Touches only AI-derived columns (signal, ai_confidence, ai_reasoning,
sentiment, relevant, prefilter_reason, analysis_version). Leaves all
market-derived columns intact (price_at_post, price_impact_*) — those
stay accurate regardless of which prompt version interpreted the post.
