/**
 * export-dev-seed.mjs
 *
 * Dumps the current dev database into packages/db/prisma/dev-seed.sql.
 * The dump is safe to commit: passwords, TOTP secrets, SMTP credentials,
 * and webhook secrets are all sanitized before writing.
 *
 * Usage:
 *   node scripts/export-dev-seed.mjs
 *
 * Requirements:
 *   - The capakraken-postgres-1 Docker container must be running
 *   - DATABASE_URL must point to a local capakraken database
