Bring back the world export/backup button for Android users

With the latest Android updates and scoped storage restrictions, players can no longer access their Minecraft worlds folder manually through file managers. Since the game often lacks the "Export World" button on many devices, our survival worlds are completely trapped in the internal storage. If we ever need to reinstall the game or switch profiles, we risk losing everything. Our worlds represent months or years of dedication and carry a huge sentimental value. Please, add a reliable, built-in feature to export, backup, or sync our worlds to the cloud on Android so we can protect our progress safely.
