Add explicit sort order to workflow runs query

Explicitly sort workflow runs by created date in descending order to ensure
early exit optimization works correctly. This makes the assumption that newer
runs appear first more explicit and reliable.

- Add sort: 'created' parameter
- Add direction: 'desc' parameter

This ensures the early exit logic (stopping when we see SHAs different from
the previous commit) works as intended.
