Generate the changelog from commits since the last nightly and pass it to
fastlane's upload_to_testflight changelog. The previous nightly's commit
SHA is stored as a dedicated nightly-build-commit artifact (independent of
the most-recent-testflight-commit cache), so the range is nightly-to-nightly.
Falls back to the last 30 commits when no prior marker is found.
Requires actions: read on the job to query past artifacts.
