- Add validate_card_names() helper: checks collection_entries DB first,
then falls back to Scryfall /cards/named?fuzzy= for unknowns.
Drops any name that cannot be resolved (hallucinated cards).
- Inject validation in Step 4 immediately after each suggest_cards()
call so hallucinated names never reach ratio enforcement or assembly.
- Log dropped hallucinations at WARNING level with count + examples.
- Resolves the 'Sonic Hedgehog Charger' / 'Sonic Boom' class of
LLM-invented card names that were silently entering the deck.
