What's Changed

Thanks to a great contribution by @​lexfrei, backports no longer fail when the target branch already contains some of the changes, for example if a specific commit was already manually cherry-picked, or on a re-run. Previously, git reported the empty cherry-pick as a conflict, so the backport failed (or opened a draft PR with conflict_resolution: draft_commit_conflicts).

Now the action skips those commits:

• Some commits already on the target: the backport PR is created as usual. The comment on the original pull request mentions the skipped commits, and a comment on the backport PR lists them.
• All commits already on the target: there's nothing to backport, so no PR is created. The target is skipped, just like when its backport PR already exists, and doesn't count as a failure in was_successful.

With comment_style: summary, that looks like this:

Target	Status
stable/8.7	✅ Created #​612 — 1 commit skipped (target already contains changes)
stable/8.6	➖ Skipped (target already contains changes)

No configuration needed to enable this. This is a bug fix released in a new minor version to avoid surprising users with new behavior.
