export reads the current App Store manual (and with --with-automatic the equalized) prices and the Play purchase
option regional prices into one CSV. import parses and checks the sheet, prints a diff table (change %), and after a
confirmation writes one App Store price schedule per changed product (base territory + every manual price, future-dated
changes via start_date, price point ids looked up per territory) and the Play regional configs (CSV over current,
convertRegionPrices for regions without a price, --reconvert). MCP: prices_diff (read-only), prices_export; applying
stays a terminal command. store-iap-setup skill: price sheet section.
