"""03 DAYTONA SANDBOX. Run untrusted code inside a Daytona sandbox. Same task as
01 and 02, a different provider. Daytona spins up a remote dev environment on
demand and tears it down when you're done with it.

Run:  python 03_daytona_sandbox.py "print('hello from daytona')"
Needs: pip install daytona, and DAYTONA_API_KEY set in your environment
(get a free key at app.daytona.io). Without a key, this script tells you what
it WOULD do and exits 0. It never fakes output.
