Diretta Assistenza

I've made the following updates to reflect changes since the initial post:

1. Noted in "2. Diretta Host PC Setup Overview" that the Diretta-related apps have been integrated into Diretta Tools.

2. Updated the Diretta URLs to reflect the recent server migration.

3. Added a new section: "13. Network Speed Settings."

初版投稿以降、変更のあった以下の更新を行いました。

① 「2 Diretta Host PCの設定概要」にDiretta関連アプリがDiretta Toolsに統合されたことを記述 

② Direttaのサーバー移転によりURLが変更された点を反映

③ 「13 通信速度設定」を追記
