Fix: Corrected Exit Status Code for convox exec Command

This update resolves an issue where the convox exec command did not always return the correct exit status code. The command now properly reflects the exit code of the executed process inside the container, ensuring accurate handling in automation scripts and CI/CD workflows.

Why is this important?

Exit status codes are crucial for scripting and automation. Previously, incorrect or inconsistent exit codes from convox exec could cause confusion or unintended behavior in automated deployments, monitoring tools, and CI/CD pipelines. This fix ensures that:

• A successful command inside the container returns a 0 exit code.
• A failed command inside the container correctly propagates its non-zero exit code.
• Scripts and automation that rely on convox exec can now function reliably without manual workarounds.

Does it have a breaking change?

No breaking changes are introduced with this update.
