fix: command arguments need to be split

[neuromantik33]

Command arguments need to be split when invoking inline scripts in pods.

[Copilot]

Pull Request Overview

This PR fixes a bug in the pod script execution where command arguments were being passed as a single string instead of being split into individual arguments. This ensures that inline scripts in pods receive properly formatted command-line arguments.

• Splits the RD_CONFIG_ARGUMENTS string into individual arguments using spaces as delimiters
• Changes from appending a single string to appending individual arguments to the exec_command list

Using split(' ') will not handle arguments that contain spaces (even when quoted) or multiple consecutive spaces correctly. Consider using shlex.split() instead, which properly handles shell-style quoting and escaping.

Thank you for identifying this bug! You're absolutely right that arguments need to be split - the current code incorrectly passes all arguments as a single string element instead of splitting them into individual arguments.

Your fix is correct and consistent with how the code already handles the invocation parameter (line 122).

One consideration: Simple space-splitting doesn't handle quoted arguments (e.g., --message "hello world"), but that's a pre-existing limitation that also affects the invocation parameter. Your change maintains consistency with the existing approach, which is the right call for this fix.

Before we can merge this, could you please:

1. Rebase on the latest master branch - there have been several updates since this PR was opened
2. Add a brief note in the PR description about what scenarios this fixes (e.g., "Fixes passing multiple arguments to inline scripts")

Thanks for the contribution!
