@copilot resolve merge conflicts

I've resolved the merge conflicts locally by rebasing onto the updated dev branch (after PR #616 was merged). The branch now contains only the fieldsToReturn fix (commit cac04f2) on top of dev.

However, I'm unable to force-push the resolved branch due to authentication constraints. The report_progress tool attempts to rebase against the remote branch which still has all 16 old commits, causing conflicts.

Could you either:

1. Grant force-push permissions, or
2. Manually reset the remote branch to match commit cac04f2 on my local branch

The fix is ready and conflicts are resolved locally - just needs the remote branch updated.

@copilot resolve merge conflicts

Merge conflicts have been resolved locally. The branch now contains only the fieldsToReturn fix (commit c4bdf7b) on top of the merged PR #616 changes.

However, the automated push system cannot handle force-pushing the rebased branch. The local branch is ready - it just needs to be force-pushed to origin/copilot/sub-pr-616.

The fix is verified and ready at commit c4bdf7b. Could you manually force-push or grant the necessary permissions?
