This PR appears to be missing critical information according to the NuttX requirements.

Here's what's lacking and needs clarification:

• Summary:
  • Why is this change necessary? What problem does setting CMOCKA_SHUFFLE_SEED solve? Is it a bug fix, performance improvement, or new feature?
  • What exactly changes? How does setting this environment variable affect the cmocka launcher's behavior?
• Impact:
  • Be specific about the impact. "cmocka launcher" is too vague. Does this affect all users of cmocka? Only specific configurations? Will existing tests behave differently?
  • Address all impact points: The template asks about build process, hardware, documentation, security, compatibility. Even if the answer is "NO," state it explicitly for each.
• Testing:
  • "ci" is not sufficient testing information.
    • Which CI environments were used? List specific architectures and boards.
    • Provide relevant snippets of the logs demonstrating the change in behavior. What were the results before and after the change?

Recommendation:

Expand on each section with specific details. This will help reviewers understand the purpose and scope of your change, leading to a faster and smoother review process.
