### POST /find_cheapest

Pass an explicit product spec. PricePilot resolves the exact variant on Amazon and Walmart in parallel and returns the cheapest currently-in-stock offer.

Required fields: `brand`, `model`. Optional: `color`, `size`, `condition`, `postal_code`, `source_scope`.

Returns: `{ product_id, best, all_offers, missing_sources, checked_at }`.

`best` is the cheapest verified buyable offer. `null` means no offer found.
