Repository Cleanup and Consolidation

I would like to suggest removing the following duplicate repositories:

* [forrtproject/forrt-mapping-from-Richard-for-backup](https://github.com/forrtproject/forrt-mapping-from-Richard-for-backup-) — a backup/duplicate repository under the FORRT organization.
* [richarddushime/forrt-mapping ](https://github.com/richarddushime/forrt-mapping)— my personal copy of the project, which I will also delete.

The current and most up-to-date version of the project is:

* [forrtproject/map-community](https://github.com/forrtproject/map-community)

All the latest updates have already been pushed to [forrtproject/map-community](https://github.com/forrtproject/map-community)

It would be better to maintain **one active repository in one place** rather than keeping multiple copies of the same project. This would make the project easier to maintain, avoid confusion about which repository is the latest version, and provide a single source of truth for future development.

まず、forrtproject/map-community が現在の信頼できる情報源であることを確認し、issue に記載されている 2 つの重複リポジトリを確認します。リポジトリ所有者による削除またはアーカイブの計画を確認し、重複リポジトリを指している参照がまだ存在するか確認します。重複コピーが削除またはアーカイブされ、map-community が唯一のアクティブなリポジトリになれば完了です。
