 * Nautilus database client.

 * Usage:
 *
 *   const db = new Nautilus();
 *   await db.connect();
 *
 *   const users = await db.user.findMany({ where: { role: 'ADMIN' } });
 *   const user  = await db.user.create({ data: { email: 'alice@example.com' } });

 *   await db.disconnect();
 *
 * Transaction usage:
 *
 *   const result = await db.$transaction(async (tx) => {
 *     const user = await tx.user.create({ data: { email: 'alice@example.com' } });
 *     await tx.post.create({ data: { title: 'Hello', authorId: user!.id } });
