Using https://modal.com/docs/guide/sandboxes, complete the following task:
Using Modal, build me a script that runs a multi-step computation inside a Modal sandbox:
1. Use the Modal Python SDK to create/connect to a sandbox
2. Inside the sandbox, execute the following pipeline:
a. Install the `sympy` package using pip
b. Run a Python script that:
- Computes the 10th Fibonacci number iteratively
- Uses sympy to check if that number is prime
- Prints the result as JSON: {"fibonacci_10": <number>, "is_prime": <boolean>}
3. Capture the sandbox execution output and print it to stdout
All computation must run inside the Modal sandbox, not in your local Python process. Do not use subprocess — use the Modal SDK's execution primitives.modal_sandbox.py
