+-- Migracja: rename kolumn products + nowe pola dla feedu XML + xml_feed_url w clients
+-- Cel: rozdzielenie danych z feedu GMC (title_gmc, description_gmc) od edytowalnych/AI (title, description)
+--      oraz dodanie obslugi feedu XML per klient (cron pobiera dane i wzbogaca products).
+-- Zalozenia:
+--   - Stare `products.name` (z Google Ads / Merchant) staje sie nowym `title` (glowna nazwa wyswietlana)
+--   - Stare `products.title` (z GMC API) staje sie `title_gmc` (zrodlowa nazwa z feedu/Merchant)
+--   - Nowe `description_gmc` przechowuje opis z feedu (oddzielnie od `description` edytowanego/AI)
+--   - Nowe `price` przechowuje cene z feedu XML
+--   - Nowe `clients.xml_feed_url` i `clients.xml_feed_last_sync_at` obsluguja import feedu
+-- Idempotentnosc: kazdy ALTER chroniony EXISTS w INFORMATION_SCHEMA.
