/**
 * Deactivation feedback for Aivastark Widget.
 *
 * When an admin clicks "Deactivate" on the Plugins screen, a small modal asks
 * why (a preset reason + optional comment + their email). On "Submit &
 * Deactivate" the browser POSTs to our admin-ajax handler, which forwards the
 * feedback to the public `wordpress-feedback` edge function before the normal
 * deactivation proceeds. "Skip & Deactivate" sends nothing.
 *
 * Nothing here blocks deactivation: the JS always follows the original
 * deactivate link, whether the feedback call succeeds, fails, or is skipped.
