/**
 * Custom migration script - why?
 * Well migration scripts aren't so complex, and we haven't found a simple enough library
 * to deserve a new dependency. We like this setup because we can customize it easily
 * and it's pretty easy to understand.
 *
 * This migration system handles both custom TypeScript migrations and
 * SQL migrations generated by Drizzle.
