This PR appears to mostly meet the NuttX requirements, but could use some improvements:

Strengths:

• Summary: Provides a clear overview of the changes made.
• Impact: Addresses all the points, even if briefly.
• Testing: Links to CI runs, demonstrating testing effort.

Areas for Improvement:

• Summary:
  • Why: Briefly explain the reasoning behind switching to cURL and using shallow clones. What benefits do these changes bring (e.g., speed, reliability, size)?
• Testing:
  • Specificity: Instead of just "CI", specify the architectures and boards tested.
  • Logs: While linking to CI is good, consider including snippets of relevant log output demonstrating the changes' effects. This provides more immediate context within the PR.
• Impact:
  • While "NO" is fine for most, elaborate slightly on any "YES" answers, even if it seems obvious. For example, "Impact on build: YES - Ninja is now required".

By addressing these points, you'll make the PR easier to review and merge.
