v0.4.1

A small release with one fix in it that matters more than its size.

A valley survives a new phone

The Android export told the system not to include the game in the device backup. Everything a child makes — their profile, their valley, what they built, what they are carrying — lives in the app's own private storage, so a family that played for a month and changed a phone would have opened an empty valley. There is no way to notice that in testing: the only symptom is a loss that happens once, to somebody else, long afterwards.

Backup is allowed now. Android copies that storage into the owner's own Google account and restores it when they set up a new device; the game neither sends it nor sees it, which is why docs/PRIVACY.md describes it as a service between the device owner and Google rather than as something this game does.

A check reads the export preset and fails if it is ever switched off again, and confirms that the profiles and the save live in the storage the backup actually covers.
