Repo Pruner

Repo Pruner is a GitHub Action designed to help maintain clean and organized repositories by monitoring inactive branches. This tool scans for branches that have been inactive for a specified duration (based on the last commit date) and automatically opens a pull request for each branch. The branch creator is assigned as the reviewer, allowing them to either merge their work or close the PR and delete the branch, ensuring your repository remains streamlined and clutter-free.
