/**
 * import-dev-seed.mjs
 *
 * Imports packages/db/prisma/dev-seed.sql into the local dev database.
 * Wipes the public schema, re-applies the current Prisma schema, loads the
 * seed data, then sets every user's password to "Dev123456!" via argon2id.
 *
 * Usage:
 *   node scripts/import-dev-seed.mjs
 *
 * Requirements:
 *   - The capakraken-postgres-1 Docker container must be running
 *   - DATABASE_URL must point to a local capakraken database
 *   - dev-seed.sql must exist (run export-dev-seed.mjs first)
