Define a module manifest

It would be helpful if this project would define a module manifest, so that I could avoid exporting java module internals to `ALL-UNNAMED` in Java 17+. I understand I would still need to add those exports, but the reduced scope would be helpful.

未指定檔案、測試或進入點。先檢查專案的建置與封裝設定是否支援 Java 17 模組，然後判斷模組資訊清單如何將匯出限制為 ALL-UNNAMED。專案定義了該資訊清單，且驗證了由此產生的匯出範圍，即表示完成。
