Swallows print Statements

Related to this [CadHub issue](https://github.com/Irev-Dev/cadhub/issues/548).

Calls to `print()` (stdout) within a script will not show up in the CadHub console, but calls to `println(..., file=sys.stderr)` (stderr) do. My guess is that this is related to how CQGI is executed from within cq-cli, but it needs to be investigated.

Start by reproducing the issue with a script that calls print() and another that writes to stderr, then inspect how CQGI is executed from cq-cli. Compare the handling of stdout with stderr in the console, using the related CadHub issue for context. Done means script stdout appears in the CadHub console while stderr continues to work.
