/**
 * Uninstall StoreCanvas Lite.
 *
 * Removes the sclt_ transient cache and the plugin's product meta
 * (option field definitions and group assignments). Option group posts
 * (sclt_option_group CPT) are kept — they are store content the merchant
 * created. Order and order-item meta (chosen options, labels, price extras,
 * and the _sclt_option_stock_applied / _sclt_option_stock_restored flags) is
 * kept — it is part of the order record a store may need to retain.
 *
 * Customer design canvas: removes the per-product canvas settings, the signing
 * secret and folder key options, the daily cleanup event, the guest upload
 * throttle transients and every file in uploads/sclt-designs (customer previews
 * and uploaded images, ordered or not). Download the design files of open orders
 * first, or define SCLT_KEEP_DESIGNS_ON_UNINSTALL as true in wp-config.php to keep
 * the files. The order-item design record (_sclt_design) stays with the order.
 *
 * Does not touch the paid StoreCanvas plugin's data.
