/**
 * This script handles the cutover for subscriptions migrating from Recurly to Stripe.
 *
 * IMPORTANT: Only run this after Stripe subscriptions have been created in Stripe and
 * are ready to take over billing from Recurly.
 *
 * NOTE: This script will trigger lifecycle emails to be sent. Please turn off:
 * - "Send emails about upcoming renewals" (https://dashboard.stripe.com/<account>/settings/billing/subscriptions)
 * - "Subscription Change Template" (https://sharelatex.recurly.com/emails/subscription_change/template/edit)
 *
 * Usage:
 *   node scripts/stripe/finalize-stripe-subscription-migration.mjs [OPTS] [INPUT-FILE]
 *
 * Options:
 *   --output PATH                 Output file path (default: /tmp/migrate_output_<timestamp>.csv)
 *   --commit                      Apply changes (without this, runs in dry-run mode)
 *   --concurrency, -c <n>         Number of customers to process concurrently (default: 10)
 *   --recurly-rate-limit N        Requests per second for Recurly (default: 10)
 *   --recurly-api-retries N       Number of retries on Recurly 429s (default: 5)
 *   --recurly-retry-delay-ms N    Delay between Recurly retries in ms (default: 1000)
 *   --stripe-rate-limit N         Requests per second for Stripe (default: 50)
 *   --stripe-api-retries N        Number of retries on Stripe 429s (default: 5)
 *   --stripe-retry-delay-ms N     Delay between Stripe retries in ms (default: 1000)
 *   --help                        Show help message
 *
 * CSV Input Format:
 *   recurly_account_code,target_stripe_account,stripe_customer_id
 *   507f1f77bcf86cd799439011,stripe-uk,cus_1234567890abcdef
 *
 * CSV Output Format:
