 * NOTE: This file exceeds 200 LOC because it aggregates all WordPress admin
 * hook wiring (notices, cron, auto-update, plugin-row notifications) into one
 * class — splitting would require injecting WP globals and create more
 * indirection without clarity gain. Acceptable exception per code standards.
 *
 *
 * Ported from YayMail Pro LicenseHandler.php — all YAYMAIL_* constants and
 * CorePlugin::get() calls replaced with $this->adapter->get_*() methods.
 * The hardcoded yaycommerce_licensing_plugins filter registration at priority 100
 * is preserved for backwards compat — new code uses LicenseRegistry instead.
 *
 * NOTE: The original LicenseHandler used CorePlugin::get() for item_id/slug/etc.
 * Here those values come from the injected LicenseConfigAdapter. Port is faithful;
 * any oddities from source preserved with // TODO: investigate comments.
