/**
 * Grammar-compat pin for the plugin job scheduler's node-cron → cron migration.
 *
 * A validation *tightening* would silently disable a published plugin's job
 * (an invalid cron is skipped, never scheduled — deliberately, so a bad
 * schedule can't take the host down). This runs the REAL `cron` validator
 * (unmocked) over the manifest shapes plugins realistically declare and pins
 * that everything node-cron accepted still schedules, and garbage still
 * doesn't.
