Validates a whole JSON file (course keys, meeting numbers, values, dates) and upserts meetings, courses, class sessions, deadlines and readings in one transaction, matched on their natural identity. Prints a created, updated and unchanged summary; --dry-run only validates. Ships a small example fixture with made-up data.
