[Bug]: `git-ai ci github run` not pulling prompt information

[andrewfrankel]

What broke?

We use github squashes for PRs, so have an action running to carry over the git-ai metadata to develop using git-ai ci github run

It's working correctly for file line attributions, but the prompts data is empty. Believe this is a bug.

  "prompts": {}
}

Steps to reproduce

1. Run git-ai ci github run on PR close
2. After merge, check contents on develop with git notes --ref=ai show, git-ai stats or similar
3. The attributions come across, but not the prompts.

Expected vs actual behavior

Expected: prompts should be filled with the data from the original branch/PR
Actual: prompt is empty {}

Diagnostics (git-ai debug)

Hey @andrewfrankel thanks for the report! Would you be able to share the notes in the commits that were squashed to help me replicate? Tried having an agent replicate, but it wasn't able to find anything useful (at least as of the latest version, which does have fixes for known issues for regressions with rebase logic)
