/**
 * Migration: 2026-05-24 — Rename @tcgvault.com user emails to @deckhearth.com
 *
 * Part of the `pick-a-name` convoy. Renames every `users.email` row matching
 * `%@tcgvault.com` to the `@deckhearth.com` equivalent (admin + alice + bob,
 * plus any other accidentally-`@tcgvault.com` users if they exist).
 *
 * Idempotent: re-running after the first run prints "Nothing to migrate."
 *
 * Usage:
 *   node scripts/migrations/2026-05-24-rename-admin-email.js
 *
 * Required env: POSTGRES_URL (read from .env.local).
 *
 * Safety: the UPDATE uses REPLACE() so emails like `admin@tcgvault.com`
 * become `admin@deckhearth.com`. The `users.email` UNIQUE constraint will
 * fail loudly if a row with the target email already exists — which is the
 * correct behavior (do NOT silently overwrite). If you see the constraint
 * violation, inspect the DB manually before retrying.
