Subject: [PATCH] fix: enhance changelog update logic to prevent infinite loops

- Added checks to skip changelog updates if the only unpushed commit is a changelog update commit.
- Improved handling of multiple unpushed commits by excluding the latest changelog commit from the diff analysis.
- Cleaned up temporary changelog preview files when no other changes are detected.
