A GitHub Action that deletes GitHub Actions caches by key prefix using the GitHub REST API. Useful for cleaning up stale or unwanted caches, for example after a pull request is merged or closed.

• Delete caches matching a key prefix
• Optionally scope deletion to a specific git ref
• Reports the number of successfully deleted caches
• Detailed logging with cache sizes and freed space
• Graceful handling of partial failures
